Thermodn. modeling of the solubilities of various acetylacetonate-type metal precursors in supercritical carbon dioxide was performed using the PC-SAFT (perturbed-chain statistical associating fluid theory) equation of state. Pure component parameters for the metal precursors (segment number, segment diameter, and dispersion energy) were determined by fitting to solubility data obtained from the literature. The PC-SAFT equation of state could correlate the literature data over wide temperature and pressure ranges for various precursors. The pure component PC-SAFT parameters obtained from these correlations were found to vary systematically with changes in the properties of the metal precursors, such as the molar masses of the precursors and of the metal centers, which could be generalized based on the phys. meaning of each parameter. The generalized PC-SAFT parameters could reproduce the solubilities of the metal precursors in supercritical carbon dioxide to within 30% average relative deviation under almost all conditions, especially at temperature below 393 K. The results came from multiple reactions, including the reaction of Bis(acetylacetone)copper(cas: 13395-16-9Related Products of 13395-16-9)

Han, Yulian; Hamada, Morihiko; Chang, I-Ya; Hyeon-Deuk, Kim; Kobori, Yasuhiro; Kobayashi, Yoichi published an article in 2021. The article was titled 《Fast T-Type Photochromism of Colloidal Cu-Doped ZnS Nanocrystals》, and you may find the article in Journal of the American Chemical Society.COA of Formula: C10H16CuO4 The information in the text is summarized as follows:

This paper reports on durable and nearly temperature-independent (at 298-328 K) T-type photochromism of colloidal Cu-doped ZnS nanocrystals (NCs). The color of Cu-doped ZnS NC powder changes from pale yellow to dark gray by UV light irradiation, and the color changes back to pale yellow on a time scale of several tens of seconds to minutes after stopping the light irradiation, while the decoloration reaction is accelerated to submillisecond in solutions This decoloration reaction is much faster than those of conventional inorganic photochromic materials. The origin of the reversible photoinduced coloration is revealed to be a strong optical transition involving a delocalized surface hole which survives over a minute after escaping from intraparticle carrier recombination due to electron-hopping dissociation ZnS NCs can be easily prepared in a water-mediated one-pot synthesis and are less toxic. Therefore, they are promising for large-scale photochromic applications such as windows and building materials in addition to conventional photochromic applications. Moreover, the present study demonstrates the importance of excited carrier dynamics and trap depths, resulting in coloration over minutes not only for photochromic nanomaterials but also for various advanced photofunctional materials, such as long persistent luminescent materials and photocatalytic nanomaterials.

The article contains the following contents:

In the present paper, the thermal behavior of Sr-Cu-O gels obtained by sol-gel (SG) or microwave (MW)-assisted SG methods was studied in order to establish the appropriate thermal conditions for pure nanostructured SrCu2O2 preparation As reagents, copper and strontium acetylacetonate in alc. media were used. The starting solutions were homogenized either by stirring for 2 h at room temperature or were exposed to MW for 5 min at 300 W and a frequency of 2.45 GHz. Both solutions were left to gel at room temperature The obtained gels were investigated by SEM, Fourier-transform IR spectroscopy, as well as by thermal anal. combined with evolved gas anal. (TG/DTA-MS) measurements in air, inert and reducing atmospheres. For both type of samples, a stepwise thermal decomposition of the gels was noticed in a large temperature range. In the case of samples obtained by microwave-assisted SG method, a higher number of thermal effects were registered assigned to a higher number of mol. species formed in the sample. The residues obtained by non-isothermal treatment up to 900°C, of both type of samples, were investigated by X-ray diffraction. The results demonstrate the influence of the MW on the SG synthesis and on the thermal properties of the resulted gels. Based on the obtained results, the required thermal treatment of the gels in order to obtain convenient precursors powders for obtaining pure SrCu2O2 could be proposed.

The article was written by Munoz-Flores, Paula; Poon, Po S.; Ania, Conchi O.; Matos, Juan. The article contains the following contents:

A carbon-containing Cu-based material (Cu@C) was used as photocatalyst for the degradation of a commonly food-industry azo-dye (tartrazine, also called Y5), under solar light at laboratory and pilot scale photoreactors. Important performance parameters such as dark adsorption capacity, catalyst’s loading and initial concentration of the dye were first optimized in a slurry photoreactor at laboratory scale under artificial solar light following the kinetics of degradation of the dye. Afterwards, the photocatalytic activity was investigated at pilot scale in a compound parabolic collector (CPC) photoreactor operating for 10 h of irradiation The degradation of tartrazine is among the highest values reported for alternative metal oxide semiconductors, in both photoreactor configurations. Catalytic data revealed a 3 times faster degradation kinetics of tartrazine in the CPC photoreactor under natural solar light than in the slurry reactor under artificial solar light. This behavior indicates that a moderate photon flux in the CPC is more adequate to operate with the prepared photocatalyst, as it minimizes the recombination of charge carriers in the catalyst. This is important, since most of the photocatalytic tests designed to evaluate the activity of novel materials are frequently carried out under simulated solar light and disregard the impact of photon flux in outdoor conditions.

《Remarkable reversal of 13C-NMR assignment in d1, d2 compared to d8, d9 acetylacetonate complexes: analysis and explanation based on solid-state MAS NMR and computations》 was written by Andersen, Anders B. A.; Pyykkonen, Ari; Jensen, Hans Joergen Aa.; McKee, Vickie; Vaara, Juha; Nielsen, Ulla Gro. Safety of Bis(acetylacetone)copperThis research focused ontransition metal acetylacetonate complex NMR; optimized mol structure transition metal acetylacetonate complex; crystal structure transition metal acetylacetonate complex. The article conveys some information:

13C solid-state MAS NMR spectra of a series of paramagnetic metal acetylacetonate complexes; [VO(acac)2] (d1, S = 1/2), [V(acac)3] (d2, S = 1), [Co(acac)3], [Ni(acac)2(H2O)2] (d8, S = 1), and [Cu(acac)2] (d9, S = 1/2), were assigned using modern NMR shielding calculations This provided a reliable assignment of the chem. shifts and a qual. insight into the hyperfine couplings. Our results show a reversal of the isotropic 13C shifts, δiso(13C), for CH3 and CO between the d1 and d2vs. the d8 and d9 acetylacetonate complexes. The CH3 shifts change from about -150 ppm (d1,2) to roughly 1000 ppm (d8,9), whereas the CO shifts decrease from 800 ppm to about 150 ppm for d1,2 and d8,9, resp. This was rationalized by comparison of total spin-d. plots and computed contact couplings to those corresponding to singly occupied MOs (SOMOs). This revealed the interplay between spin delocalization of the SOMOs and spin polarization of the lower-energy MOs, influenced by both the mol. symmetry and the d-electron configuration. A large pos. chem. shift results from spin delocalization and spin polarization acting in the same direction, whereas their cancellation corresponds to a small shift. The SOMO(s) for the d8 and d9 complexes are σ-like, implying spin-delocalization on the CH3 and CO groups of the acac ligand, canceled only for CO by spin polarization. In contrast, the SOMOs of the d1 and d2 systems are π-like and a large CO-shift results from spin polarization, which accounts for the reversed assignment of δiso(13C) for CH3 and CO.

We present the synthesis of metal nanowires in a multiplexed device configuration using single-walled carbon nanotubes (SWNTs) as nanoscale vector templates. The SWNT templates control the dimensionality of the wires, allowing precise control of their size, shape, and orientation; moreover, a solution-processable approach enables their linear deposition between specific electrode pairs in electronic devices. Elec. characterization demonstrated the successful fabrication of metal nanowire electronic devices, while multiscale characterization of the different fabrication steps revealed details of the structure and charge transfer between the material encapsulated and the carbon nanotube.

Quality Control of Bis(acetylacetone)copper The author mentioned the following in the article:

Core-shell architecture coupled with rational surface engineering constitutes an efficient strategy for promoting electrocatalysis on multimetallic nanocrystals via the optimization of composition, facets and coordination environment. Here, by leveraging controlled surface segregation, we realize core-shell formation with systematic tuning of surface composition on well-defined PdCuRu nanocrystals. When applied for the hydrogen evolution reaction (HER), we established a direct correlation between surface composition and activity. In particular, PdCuRu catalysts with a Pd-rich surface achieved an overpotential of 31 mV at a c.d. of 10 mA cm-2 and a low Tafel slope of 52 mV dec-1 in an alk. electrolyte, considerably enhanced relative to control PdCuRu/C catalysts with other surface compositions and even exceeding those of state-of-the-art Pt/C. Similar trends were also observed in both neutral and acid electrolytes. We deduce that, in this catalytic system, the enhanced electrocatalysis originates from the strain effect rather than the bifunctional mechanism. The present study builds a bridge between surface engineering and HER performance, and opens up new material designs for surface Pd-rich core-shell nanostructures for the purpose of improving HER catalytic activity and stability at all pH values.

The author of 《The controllable growth of PtCuRh rhombic dodecahedral nanoframes as efficient catalysts for alcohol electrochemical oxidation》 were Wang, Zhen; Huang, Lei; Tian, Zhi Qun; Shen, Pei Kang. And the article was published in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2019. Application of 13395-16-9 The author mentioned the following in the article:

Platinum-based catalysts with heterogeneous structures, such as three-dimensional (3D) nanoframes and highly branched architectures, have broad application prospects due to their fully accessible surfaces and high atom utilization. However, the fragile frames and dendrites with high energy easily suffer from structural collapse during catalytic processes. Hence, we synthesized Rh-strengthened PtCuRh rhombohedral dodecahedrons with nanodendrites (RDD) through a one-pot solvothermal method, which could be etched to obtain totally open nanoframe PtCuRh rhombohedral dodecahedrons with nanodendrites (RDND). More interestingly, the growth of the nanodendrites can be easily controlled through changing the reaction temperature Meanwhile, the length of the nanodendrites can be controlled through adjusting the amount of CTAB and the reaction time. In addition, synergistic effects between Pt, Cu and Rh modified the electronic structure; in particular Rh metal oxide on the surface contributes heavily towards improving the electrocatalytic efficiency. Therefore the as-prepared catalyst PtCuRh RDND shows superior catalytic performance towards the methanol oxidation reaction (MOR) as well as the ethanol oxidation reaction (EOR) compared to TKK-com. Pt/C. Remarkably, after 1000 electrochem. cycles of the MOR, the superior mass activity of PtCuRh RDND surpasses that of TKK-com. Pt/C by 2.6 times, benefiting from enhanced CO tolerance and the stable structure. This work provides a facile and feasible strategy for synthesizing stable and efficient nanoframe catalysts. In the part of experimental materials, we found many familiar compounds, such as Bis(acetylacetone)copper(cas: 13395-16-9Application of 13395-16-9)
