Facile preparation of highly active and stable CuO-CeO2 catalysts for low-temperature CO oxidation via a direct solvothermal method

CuO-CeO2 catalysts with different CuO contents prepared via a direct solvothermal method with superior activity as well as excellent water vapor resistance and good stability have been successfully developed for the catalytic oxidation of CO at low temperatures. The catalyst with a Cu/Ce ratio of 2 : 8 (mol/mol) delivers a high CO conversion of 90% at 86 degrees C, and particularly, is stable for at least 50 h even in the presence of water vapor without deactivation. By extensive characterization including ICP-AES, XRD, N-2 adsorption measurement, Raman, XPS, H-2-TPR, CO-TPD, and in situ DRIFTs, it was found that the presence of abundant oxygen vacancies and strong interaction between CuO and CeO2 are responsible for the excellent catalytic performance of the CuO-CeO2 catalysts for low-temperature CO oxidation.

Copper molybdate nanoparticles for electrochemical water splitting application

Two different phases of copper molybdate nanoparticles such as Cu3Mo2O9 and Cu6Mo5O18 were synthesized through schematic hydrothermal treatment. The obtained product morphology was explored by using surfactants like sodium lauryl sulfate (SDS) and polyvinylpyrrolidone (PVP). The structural, optical, vibrational and morphological properties were confirmed employing standard characterization techniques. Rectangular nanoflakes of the obtained product were confirmed by employing Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies. Selected area electron diffraction (SAED) pattern confirms obtained product crystalline nature. The better morphology controlled sample gives higher 227 mA/g current density at 10 mV/s and small 184 V overpotential. Long duration stability over 16 h was exhibited by Cu6Mo5O18 electrode. Hence, Cu6Mo5O18 electrode shows better electrochemical activity with stunning low overpotential. It would be suggested that PVP surfactant is quite optimum to produce efficient Cu6Mo5O18 catalysts for electrochemical water splitting applications. (c) 2020 Hydrogen Energy Publications LLC.

Insight into Fructose Dehydration over Lewis Acid alpha-Cu2P2O7 Catalyst

Key information on direct conversion of fructose into 5-hydroxymethylfurfural (5-HMF) over Lewis acid sites was investigated by combining experimental and computational studies. A series of alpha-copper pyrophosphate (alpha-Cu2P2O7) was synthesized and used as a heterogeneous catalyst model for bifunctional acid-catalyzed fructose dehydration under hot compressed water at mild temperature. Structural and phase transformations of the catalyst samples were systematically characterized by in situ X-ray absorption spectroscopy (in situ XAS), X-ray powder diffraction (XRD) and Transmission electron microscopy (TEM). The type of acidic site was verified by in situ pyridine-adsorbed Fourier-transform infrared spectroscopy (in situ Py-FTIR). Results revealed that calcination temperature greatly impacted microstructure, acid strength, and activity of the alpha-Cu2P2O7 catalysts. Lewis acid sites showed the main activity on alpha-Cu2P2O7 catalyst surfaces. Catalytic performance was strongly dependent on reaction temperature and reaction time. Under optimal reaction condition, the calcined sample at 900 degrees C exhibited the best catalytic performance with 5-HMF production yield of 42.0%. Results from density functional theory (DFT) revealed that fructose dehydration over alpha-Cu2P2O7 catalyst was enhanced by increasing reaction thermodynamics via Lewis acid sites.

Copper and manganese bimetallic catalysts for oxidation of prot lignin: effects of metal oxide on product yield

Lignin is a macro polymer with aromatic structure and is a highly promising renewable carbon source for valuable chemicals and energy. It is available in huge quantities as a by-product from the paper & pulp industry and 2G ethanol industry. Valorization of lignin into useful chemicals can play a vital role in overcoming the demand of diverse chemicals being produced from petroleum feedstock. In the present study, we have examined the oxidative conversion of prot lignin in the presence of Cu/gamma-Al2O3, Mn/gamma-Al2O3, and Cu-Mn/gamma-Al2O3 in water and ethanol-water co-solvent mixture. In water, maximum bio-oil yield of 24.0 wt.% was noticed with Cu/gamma-Al2O3. In the case of ethanol-water (50/50) (wt/wt) co-solvent mixture, the maximum bio-oil yield of 74.3 wt.% was obtained with Cu/gamma-Al2O3, catalyst. The bio-oil was analysed by GC-MS, H-1-NMR, and FT-IR analyses. The GC-MS compounds were grouped as phenolic (G-, H-, and S-type), heterocyclic, acidic, and other type compounds. Among all the catalysts, Cu/gamma-Al2O3 showed the maximum amount of phenolics (84.2%) using 25/75 (wt/wt) ethanol-water solvent. In the case of water as reaction medium, the non-catalytic and catalytic oxidation of lignin showed the maximum selectivity towards acetosyringone with area percentage as 42.0% and 34.4% respectively. In addition, the formation of vanillin (20.7%) was observed in the presence of Cu/gamma-Al2O3 using water.

Multi-slice ptychography enables high-resolution measurements in extended chemical reactors

Ptychographic X-ray microscopy is an ideal tool to observe chemical processes under in situ conditions. Chemical reactors, however, are often thicker than the depth of field, limiting the lateral spatial resolution in projection images. To overcome this limit and reach higher lateral spatial resolution, wave propagation within the sample environment has to be taken into account. Here, we demonstrate this effect recording a ptychographic projection of copper(I) oxide nanocubes grown on two sides of a polyimide foil. Reconstructing the nanocubes using the conventional ptychographic model shows the limitation in the achieved resolution due to the thickness of the foil. Whereas, utilizing a multi-slice approach unambiguously separates two sharper reconstructions of nanocubes on both sides of the foil. Moreover, we illustrate how ptychographic multi-slice reconstructions are crucial for high-quality imaging of chemical processes by ex situ studying copper(I) oxide nanocubes grown on the walls of a liquid cell.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2568-25-4, in my other articles. Formula: C10H12O2.

Fabrication of RGO/PANI-supported Pt/Cu nanoparticles as robust electrocatalyst for alkaline methanol electrooxidation

In this study, polyaniline (PANI), prepared through an in-situ polymerization technique, was combined with reduced graphene oxide (RGO) nanosheets to serve as a promising substrate for bimetallic platinum-copper (PtCu) catalyst in the form of RGO/PANI/Pt/Cu. Transmission Electron Microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) analyses were conducted to study the physicochemical properties of the fabricated RGO/PANI/Pt/Cu. Electrochemical features of the proposed structure were investigated via cyclic voltammetry (CV), linear sweep voltammetry (LSV), and chronoamperometry (CA) techniques. According to the results, employing the RGO/PANI nanocomposite as a support layer, and fabricating Pt/Cu alloys resulted in not only outstanding electrochemical performance but also high durability in the methanol oxidation reaction (MOR). The onset potential (- 0.54 V) and peak current density (60.51 mA cm(-2)) of the RGO/PANI/Pt/Cu electrocatalyst were substantially improved compared with those of pure Pt electrocatalyst (- 0.44 V and 23.35 mA cm(-2)) in the MOR. Furthermore, the appropriate catalytic activity and stability of the RGO/PANI/Pt/Cu in the MOR were confirmed by 150-scan CV measurements.

In situ FTIR and ex situ XPS/HS-LEIS study of supported Cu/Al2O3 and Cu/ZnO catalysts for CO2 hydrogenation

Cu-based catalysts are commonly used in industry for methanol synthesis. In this study, supported catalysts of 5 wt% Cu/Al2O3 and 5 wt% Cu/ZnO were prepared, and their surface characteristics during H-2 reduction and CO2 hydrogenation were investigated using in situ Fourier transform infrared spectroscopy (FTIR), ex situ X-ray photoelectron spectroscopy, and high sensitivity low energy ion scattering spectroscopy. During the H-2 reduction and CO2 hydrogenation processes, it was found that Al2O3 can stabilize Cu+. In situ FTIR spectra indicated that the 5 wt% Cu/Al2O3 can adsorb large amounts of bicarbonate and carbonate species, which then convert into formate during CO2 hydrogenation. For the 5 wt% Cu/ZnO, it was found that Cu nanoparticles were gradually covered by a highly defective ZnOx overlayer during H-2 reduction, which can effectively dissociate H-2. During CO2 hydrogenation, the adsorbed bicarbonate or carbonate species can convert into formate and then into a methoxy species. Using these surface sensitive methods, a more in-depth understanding of the synergistic effect among the Cu, Al2O3, and ZnO components of Cu-based catalysts was achieved.
