Rationally engineering the surface physicochem. properties of nanomaterials can improve their activity and durability for various electrocatalytic and energy conversion applications. Cu-Pd/Ir (CPI) nanospheres (NSs) anchored on N-doped porous graphene (NPG) [(CPI NSs/NPG)] have been recently demonstrated as a promising electrocatalyst for the alk. ethanol oxidation reaction (EOR); to further enhance their electrocatalytic performance, the NPG-supported CPI NSs are coated with Au submonolayer (SML) shells (SMSs), through which their surface physicochem. properties can be tuned. CPI NSs/NPG is prepared by the previously developed method and possesses the special structures of composition-graded Cu1Pd1 and surface-doped Ir0.03. The Au SMSs with designed surface coverages are formed via an electrochem. technol. involving incomplete Cu underpotential deposition (UPD) and Au3+ galvanic replacement. A distinctive volcano-type relation between the EOR electrocatalytic activity and the Au-SMS surface coverage for CPI@AuSML NSs/NPG is revealed, and the optimal CPI@Au1/6ML NSs/NPG greatly surpasses com. Pd/C and CPI NSs/NPG in electrocatalytic activity and noble metal utilization. More importantly, its electrocatalytic durability in 1 h chronoamperometric and 500-cycle potential cycling degradation tests is also significantly improved. According to detailed physicochem. characterizations, electrochem. analyses, and d. functional theory calculations, the promoting effects of the Au SMS for enhancing the EOR electrocatalytic activity and durability of CPI NSs/NPG can be mainly attributed to the greatly weakened carbonaceous intermediate bonding and properly increased surface oxidation potential. This work also proposes a versatile and effective strategy to tune the surface physicochem. properties of metal-based nanomaterials via incomplete UPD and metal-cation galvanic replacement for advancing their electrocatalytic and energy conversion performance.

And the article was published in Angewandte Chemie, International Edition in 2019. Recommanded Product: Bis(acetylacetone)copper The author mentioned the following in the article:

We predict that the magnetic properties of [Cu(acac)2], an elastically flexible crystal, change drastically when the crystal is bent. It is found that unbent [Cu(acac)2] is an almost perfect Tomonaga-Luttinger liquid Broken-symmetry d.-functional calculations reveal that the magnetic exchange interactions along the chains are an order of magnitude larger than the interchain exchange. The geometrically frustrated interchain interactions cannot magnetically order the material at any exptl. accessible temperature The ordering temperature (TN), calculated from the chain-RPA, increases by 24 orders of magnitude when the material is bent. We demonstrate that geometric frustration both suppresses TN and enhances the sensitivity of TN to bending. In [Cu(acac)2], TN is extremely sensitive to bending but remains too low for practical applications, even when bent. Partially frustrated materials could achieve the balance of high TN and good sensitivity to bending required for practical applications of mechanomagnetic elastic crystals.

The author of 《Measuring the mechanical properties of flexible crystals using bi-modal atomic force microscopy》 were Dupont, Madeleine F.; Elbourne, Aaron; Mayes, Edwin; Latham, Kay. And the article was published in Physical Chemistry Chemical Physics in 2019. Application In Synthesis of Bis(acetylacetone)copper The author mentioned the following in the article:

Flexible crystals are an emerging class of material with unique properties and a range of potential applications. Their relatively recent development means that mech. characterization protocols have not yet been widely established. There is a lack of quant. flexibility measurements, such as the elastic modulus (Young’s modulus), reported in the literature. In this work, we investigate amplitude modulated-frequency modulated at. force microscopy (AM-FM AFM) as a fast, versatile method for measuring the elastic modulus of single flexible crystals. Specifically, the elastic modulus of single crystals of copper(II) acetylacetonate (Cu(acac)2) was measured. The elastic modulus for Cu(acac)2 was found to be 4.79 ± 0.16 GPa. Importantly, this technique was able to map the variation in mech. properties over the surface of the material with nanoscale resolution, showing some degree of correlation between surface morphol. and elastic modulus. Addnl., the distribution of elastic modulus values can be measured at different locations on the crystal, giving a statistically robust distribution, which cannot be achieved using other methods.

U.; Zhanabaeva, A. K.. HPLC of Formula: 13395-16-9This research focused ontributyl phosphate catalytic phosphorus extractant. The article conveys some information:

By kinetics, volumetry, gas chromatog., elemental anal., IR, NMR spectroscopy the oxidative alkoxylation of yellow phosphorus to phosphorus esters in alc. solutions of copper and iron salts was studied using oxygen as an oxidant. The effect of temperature, oxygen partial pressure, nature and concentration of reagents was investigated on the phosphorus conversion. The novelty and relevance of research is associated with the development of “”chlorine-free”” direct syntheses of esters of phosphorus acids from phosphorus and alcs. It was established that copper halides are characterized by the highest catalytic activity at a 5-10 optimal ratio of CuX2/P4 and a temperature of 60°C. The partial pressure of oxygen does not significantly affect the yield of phosphorus acid esters. Enlarged laboratory tests of the catalytic synthesis of tri-Bu phosphate from yellow phosphorus and butanol were carried out under optimal conditions, in which the amount of phosphorus added to the reaction was increased 20-40 times as compared with exptl. studies.

In response to the scarcity of precious metals, the development of precious-metal-saving electrocatalysts exhibiting high mass activity (MA) and durability towards oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) for both proton-exchange membrane fuel cells (PEMFCs) and direct methanol fuel cells (DMFCs) has aroused increasing attention. In this study, octahedral Cu-rich PtCu alloy is seeded to fabricate near-surface composition-tunable PtCu hollow octahedral nanoparticles (HONs) with the wall thickness of ∼2.1 nm. Due to both the alloying effects of near surface and the special hollow octahedral structure, the PtCu/C HONs exhibit significantly higher MA and durability than com. Pt/C towards both ORR in alk. medium and MOR in sulfuric acid electrolyte. The ORR MA of Pt44.1Cu55.9/C HONs are up to 2.60 A mg-1Pt that is 18.5-fold enhancement compared with that of Pt/C. Besides, after 10,000 voltage cycles, the MA of Pt44.1Cu55.9/C HONs remains to be 1.61 A mg-1Pt, a datum 53.7 times that of Pt/C. The in situ CO polarization curves exhibit that the Pt44.1Cu55.9 HONs/C own high resistance to CO poisoning. For MOR in sulfuric acid electrolyte, the optimum SA/MA of PtCu/C HONs is 5.33 mA cm-2/1.94 A mg-1Pt, which is 10.25/5.87 times higher than that of Pt/C. This study provides effective bifunctional cathode and anode electrocatalysts for both PEMFCs and DMFCs.

COA of Formula: C10H16CuO4In 2020 ,《Thermoelasticity of Flexible Organic Crystals from Quasi-harmonic Lattice Dynamics: The Case of Copper(II) Acetylacetonate》 was published in Journal of Physical Chemistry Letters. The article was written by Maul, Jefferson; Ongari, Daniele; Moosavi, Seyed Mohamad; Smit, Berend; Erba, Alessandro. The article contains the following contents:

A computationally affordable approach, based on quasi-harmonic lattice dynamics, is presented for the quantum-mech. calculation of thermoelastic moduli of flexible, stimuli-responsive, organic crystals. The methodol. relies on the simultaneous description of structural changes induced by thermal expansion and strain. The complete thermoelastic response of the mech. flexible metal-organic Cu(II) acetylacetonate crystal is determined and discussed in the temperature range 0-300 K. The elastic moduli do not just shrink with temperature but they do so anisotropically. The present results clearly indicate the need for an explicit account of thermal effects in the simulation of mech. properties of elastically flexible organic materials. Indeed, predictions from standard static calculations on this flexible metal-organic crystal are off by up to 100%.

Core/shell nanocatalysts are a class of promising materials, which achieve the enhanced catalytic activities through the synergy between ligand effect and strain effect. However, it has been challenging to disentangle the contributions from the two effects, which hinders the rational design of superior core/shell nanocatalysts. Herein, we report precise synthesis of PdCu/Ir core/shell nanocrystals, which can significantly boost oxygen evolution reaction (OER) via the exclusive strain effect. The heteroepitaxial coating of four Ir at. layers onto PdCu nanoparticle gives a relatively thick Ir shell eliminating the ligand effect, but creates a compressive strain of ca. 3.60%. The strained PdCu/Ir catalysts can deliver a low OER overpotential and a high mass activity. D. functional theory (DFT) calculations reveal that the compressive strain in Ir shell downshifts the d-band center and weakens the binding of the intermediates, causing the enhanced OER activity. The compressive strain also boosts hydrogen evolution reaction (HER) activity and the strained nanocrystals can be served as excellent catalysts for both anode and cathode in overall water-splitting electrocatalysis.

2D metal-organic framework (MOF) film as the active layer show promising application prospects in various fields including sensors, catalysis, and electronic devices. However, exploring the application of 2D MOF film in the field of artificial synapses has not been implemented yet.

《Enhanced oxygen reduction activity of PtCu nanoparticles by morphology tuning and transition-metal doping》 was published in International Journal of Hydrogen Energy in 2020. These research results belong to Wu, Dengfeng; Yang, Yang; Dai, Changqing; Cheng, Daojian. Formula: C10H16CuO4 The article mentions the following:

Developing active and durable electrocatalysts for oxygen reduction reaction (ORR) is of great significance in proton exchange membrane fuel cells (PEMFCs). Herein, a facile strategy is developed to synthesize PtCu nanoparticles with enhanced ORR performance through morphol. tuning and transition-metal doping. Two distinct PtCu nanoparticles, namely nanooctahedrons (NOs) and nanospheres (NSs), are selectively synthesized in presence or absence of W(CO)6 via a facile one-pot method. Furthermore, by introducing a small amount of third transition metal, M-doped (M = Sc, Y, La, Gd, Fe) PtCu NOs are obtained. Electrocatalytic results suggest that the ORR performance of PtCu NOs is better than that of PtCu NSs due to the morphol. advantages. And the ORR performance of PtCuM NOs is further promoted since the doping effect of transition metals compared to that of PtCu NOs. Particularly, PtCuSc NOs exhibit remarkable mass activity (1.652 mA μg-1Pt) and specific activity (2.093 mA cm-2), which are 9.9 and 7.2 times higher than that of com. Pt/C catalysts at 0.8 V (vs. RHE). Moreover, after accelerated stability tests, the loss of mass activity for PtCuSc NOs is only 9.2%, which is much lower than that of PtCu NOs (16.5%) and com. Pt/C (44.3%). This work provides a feasible idea to boost the ORR performances of Pt-based nanoparticles.
