In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Lean NOx reduction by CO at low temperature over bimetallic IrRu/Al2O3 catalysts with different Ir : Ru ratios, published in 2020, which mentions a compound: 14898-67-0, mainly applied to lean exhaust gas nitrogen oxide catalytic reduction carbon monoxide; alumina supported iridium ruthenium bimetallic reduction catalyst; low temperature reduction exhaust gas nitrogen oxide carbon monoxide, Application of 14898-67-0.

IrRu/Al2O3 bimetallic catalysts with various Ir:Ru ratios were prepared for the reduction of exhaust gas NO by CO under lean conditions. catalyst activity and physicochem. properties of IrRu/Al2O3 catalysts caused by introducing Ru on Ir in different amounts was assessed. bi-metallic IrRu catalysts were prepared by co-impregnation of Ir and Ru on the Al2O3 support, where the total combined amount of IR and Ru was kept constant IrRu bi-metallic catalysts were characterized by x-ray diffraction (XRD), H2 temperature-programmed reduction, CO chemisorption, H2 temperature-programmed desorption, transmission electron microscopy, EDS-mapping, and XPS analyses. activity results indicated IrRu bi-metallic catalysts drastically enhanced de-NOx activity in a low-temperature region; monometallic Ir and Ru catalysts exhibited diminished or even zero NOx reduction activity. a detailed examination of XRD patterns and SEM/energy dipersive x-ray mapping analyses implied formation of an IrRu alloy following reduction thus, the synergetic effect between Ir and Ru was expected to originate from the intrinsic characteristics of the IrRu alloy phase vs. Ir and Ru acting sep. as independent dual active sites. utilization of bi-metallic IrRu catalysts for NOx reduction by CO (reductant) under lean conditions was expected to enable highly efficient NOx reduction at low temperature without needing urea-based reductants, even under oxidative conditions.

From this literature《Lean NOx reduction by CO at low temperature over bimetallic IrRu/Al2O3 catalysts with different Ir : Ru ratios》,we know some information about this compound(14898-67-0)Application of 14898-67-0, but this is not all information, there are many literatures related to this compound(14898-67-0).

Author is Sharma, Poonam; Solanki, Mohit; Sharma, Rakesh K..

In this study, the oxidative conversion of 5-hydroxymethylfurfural into essential chems. on recyclable metal (Pt, Pd, Ru, Co, & Ni)- supported catalysts is reported. While most of the catalytic reactions require a base as an additive, this current study provided a base-free environmentally benign heterogeneous catalytic system. The reactions were performed on various M/CNT catalysts. As a support, CNT played an important role in the reaction mechanism. These catalysts showed a high activity for the base free oxidation of HMF under air in aqueous media. The CNT-supported Pt, Pd, and Ru catalysts were found to be more selective towards FDCA (>97%) compared to Ni and Co for DFF (>96%). The conversion and selectivity of the products were determined using NMR and HPLC. The (1 wt%) M/CNT catalysts were prepared via solution processing and were characterized using BET, XRD, TEM, TGA, FTIR, and XPS.

Quality Control of Ruthenium(III) chloride xhydrate. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Ru-embedded 3D g-C3N4 hollow nanosheets (3D CNHNS) with proficient charge transfer for stimulating photocatalytic H2 production. Author is Tahir, Beenish; Tahir, Muhammad; Nawawai, Mohd Ghazali Mohd; Khoja, Asif Hussain; Haq, Bakhtiar Ul; Farooq, Wasif.

In the recent development of structured materials, efficient and low-cost materials are highly demanding for hydrogen production In this work, novel 3D graphitic carbon nitride hollow nanosheets (CNHNS) with controlled morphol. loaded with Ru for photocatalytic hydrogen production has been investigated. Compared to CN, CNHNS improves H2 evolution of 2 times due to hollow structure with higher light absorption and proficient separation of charges within 3D structure. The highest H2 evolution was attained over 3% Ru loaded CNHNS with yield rate of 1580μmol g-1 h-1, which was 11.9 times higher than it was evolved over CNHNS and 15.1 times more than using CN, resp. This obvious augmented photoactivity can be assigned to boosted charges separation in hollow structure, whereas, Ru further promoted the transfer of electrons. The performance of 3D Ru/CNHNS was further increased in an externally reflected solar system, which was 1.30 times more than using photoreactor without reflector. This was evidently due to increasing light intensity inside the reactor by reflecting light, thus, promoting quantum efficiency under the same source of light. The stability results further confirm continuous H2 evolution even after six cycles. Thus, newly developed method for synthesis of hierarchical 3D hollow structures and externally reflector solar photoreactor will provide new directions for hydrogen production systems.

Formula: Cl3H2ORu. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Sol-Gel Synthesis of Ruthenium Oxide Nanowires To Enhance Methanol Oxidation in Supported Platinum Nanoparticle Catalysts.

A template-directed, sol-gel synthesis is utilized to produce crystalline RuO2 nanowires. Crystalline nanowires with a diameter of 128 ± 15 nm were synthesized after treating the nanowires at 600 °C in air. Anal. of these nanowires by X-ray powder diffraction revealed the major crystalline phase to be tetragonal RuO2 with a small quantity of metallic ruthenium present. Further anal. of the nanowire structures by high-resolution transmission electron microscopy reveals that they are polycrystalline and are composed of interconnected, highly crystalline, nanoparticles having an average size of ∼25 nm. Uniform 3 nm Pt nanoparticles were dispersed on the surface of RuO2 nanowires using an ambient, solution-based technique yielding a hybrid catalyst for methanol oxidation Linear sweep voltammograms (LSVs) and chronoamperometry performed in the presence of methanol in an acidic electrolyte revealed a significant enhancement in the onset potential, mass activity, and long-term stability compared with analogous Pt nanoparticles supported on com. available Vulcan XC-72R carbon nanoparticles. Formic acid oxidation LSVs and CO stripping voltammetry revealed that the RuO2-supported Pt nanoparticles exhibit significantly higher CO tolerance, which leads to higher catalytic stability over a period of several hours. XPS results suggest that crystalline RuO2 leads to less-significant oxidation of the Pt surface relative to more widely studied hydrous RuO2 supports, thereby increasing catalytic performance.

Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 14898-67-0, is researched, Molecular Cl3H2ORu, about Synthesis of ultrafine ruthenium phosphide nanoparticles and nitrogen/phosphorus dual-doped carbon hybrids as advanced electrocatalysts for all-pH hydrogen evolution reaction, the main research direction is ruthenium phosphide nanoparticle nitrogen phosphorus carbon electrocatalyst; nanoparticle electrocatalyst hydrogen ion concentration evolution reaction.Application of 14898-67-0.

Pt-group metal phosphides are widely utilized as efficient electrocatalysts for hydrogen evolution reaction (HER), whereas most of the synthetic strategies are complicated, dangerous, and toxic with the use of large amount of nitrogen (N) and/or phosphorus (P) sources. Here, we report the synthesis of ruthenium phosphide nanoparticles (NPs) confined into N/P dual-doped carbon by pyrolyzing self-prepared ruthenium-organophosphine complex using 1,3,5-triaza-7-phosphadamantane (PTA) as the ligand and N/P sources. The achieved S-RuP2/NPC displayed excellent electrocatalytic activity (overpotentials of 19, 37, and 49 mV in alk., neutral, and acidic media, resp., at 10 mA cm-2) toward HER at all pH ranges. The high performance of S-RuP2/NPC must be ascribed to the homogeneously distributed and P-rich RuP2 NPs with the diameter of 3.29 nm on the NPC surface, which can considerably improve the atom utilization for HER. The present synthetic strategy not only avoids the use of addnl. N/P sources but also the generation of flammable and toxic PH3 gas. This synthetic strategy can be extended to prepare other traditional metal phosphides for electrocatalytic applications.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Ruthenium(III) chloride xhydrate(SMILESS: Cl[Ru](Cl)Cl.[H]O[H],cas:14898-67-0) is researched.Computed Properties of C18H34BF4P. The article 《Tailoring electrochemical efficiency of hydrogen evolution by fine tuning of TiOx/RuOx composite cathode architecture》 in relation to this compound, is published in International Journal of Hydrogen Energy. Let’s take a look at the latest research on this compound (cas:14898-67-0).

Here we report an approach to design composite cathode based on TiOx nanotubes decorated with RuOx nanowhiskers for efficient hydrogen evolution. We tailor catalytic activity of the cathodes by adjustment of morphol. of TiOx nanotubular support layer along with variation of RuOx loaded mass and assess its performance using electrochem. methods and wavelet anal.The highest energy efficiency of hydrogen evolution is observed in 1 M H2SO4 electrolyte to be ca. 64% at -10 mA/cm2 for cathodes of the most developed area, i.e. smaller diameter of tubes, with enhanced RuOx loading. The efficiency is favored by detachment of small hydrogen bubbles what is revealed by wavelet anal. and is expressed in pure noise at wavelet spectrum. At increased c.d., -50 or -100 mA/cm2, better efficiency of composite cathodes is supported by titania nanotubes of larger diameter due to an easier release of large hydrogen bubbles manifested in less periodic events appeared in the frequency region of 5-12 s at the spectra.We have shown that efficiency of the catalysts is determined by a pre-dominant type of hydrogen bubble release at different operation regimes depending on sp. surface and a loaded mass of ruthenia.

Author is Appia, Foffie Thiery Auguste; Pohan, Lemeyonouin Aliou Guillaume; Berte, Mohamed; Ouattara, Lassine.

This work aimed to compare the stability, service lifetime, and electrooxidation performance of Ti/Ta2O5/Pt-RuO2-IrO2 (PRI) and Ti/Ta2O5/Pt (Pt) electrodes thermally prepared The service lifetime study performed under 410 mA/cm2 in a 9N H2SO4 showed that PRI electrode had six (06) times longer lifetime than the Pt electrode. Bulk electrolysis experiments were carried out on Pt and PRI under 20 mA/cm2. COD removal, current efficiency (CE), specific energy consumption (SEC), elec. energy cost, and anode efficiency (η) were estimated Both electrodes lead to the conversion of the parent compounds However, the Pt electrode was best suited for amoxicillin (AMX) electrooxidation with 36.89% by COD removal in KClO4 0.1 M. Besides, the PRI electrode provided the best performances for the AMX electrooxidation (8.15%) and telebrix (TLX) (29.28%) in HClO4 0.1 M and KClO4 0.1 M, resp. The presence of NaCl enhanced significantly the organic compound electrooxidation in terms of COD removal, CE, SEC, elec. energy cost, and η on the both electrodes. This is probably because of the co-action of direct and indirect (by active chlorine) oxidations But the PRI electrode presented the best performance in the presence of chloride ions. In summary, the exptl. conditions can determine the performance of an anode.

Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. Electric Literature of 13395-16-9, Name is Bis(acetylacetone)copper, Electric Literature of 13395-16-9, molecular formula is C10H16CuO4. In a article，once mentioned of Electric Literature of 13395-16-9

The hexagonal copper-tin alloy (Cu-Sn) nanoplates were synthesized using a high temperature solvent method, the length of six equilateral edges of hexagonal Cu-Sn nanoplates was 23 nm, and the thickness was 13 nm. The obtained hexagonal Cu-Sn nanoplates were highly monodisperse and allowed the formation of nanoarrays arranged with long-range order. The hexagonal Cu-Sn nanoplates exhibited high catalytic activity on catalytic hydrogenation of 4-nitrophenol to 4-aminophenol. Due to the promotion effect of Sn, the apparent rate constant (ka) of hexagonal Cu-Sn nanoplates was three times that of Cu nanoparticles. The density functional theory (DFT) calculations and experimental results demonstrated that Sn could promote the coordination process of -NO2 of 4-nitrophenol with Cu-Sn nanoplates and contribute to activation of 4-nitrophenol. In addition, the hexagonal Cu-Sn nanoplates showed high stability and reusability for the reduction reaction, good adaptability in different pH and the ionic strength, and wide applicability for the degradation of methylene blue, methyl orange, and rhodamine B, even in the industrial wastewater, suggesting that the Cu-Sn nanoplates are promising catalysts in organic industry wastewater treatment.
