In this study the influence of metal dispersion, spinel formation, and surface properties binary ternary catalysts (CuOCeO2, ZnOCeO2, CuOZnOCeO2, CuOZnOAl2O3) was evaluated. The prepared by polyol method using polyethylene glycol as a solvent have been tested in CO2 hydrogenation to methanol performed at atmospheric pressure. presented improved terms oxide morphology (i.e. sponge-like shape for CeO2-containing catalysts), large variety species on surface. Moreover, CuOZnOCeO2 CuOZnOAl2O3...
The influence of working pressure on the mechanisms CO2/H2 reaction a co-precipitated CuO/ZnO/Al2O3 catalyst have been studied at 230 °C and in range 1–75 bar. In CO2 hydrogenation using CuO/ZnO/Al2O3, products were found to be CO, methanol water almost exclusively. Only trace methane formation was observed. Methanol carbon monoxide are competitively formed. former is produced directly from whatever whereas stems either high or both decomposition low pressure.
In the present paper, coupling reaction of aldehyde, terminal alkyne, amine salt and CO2 was investigated. Copper iodide found to be an efficient catalyst for in ethyl acetate at 80 °C under atmospheric pressure CO2. A diverse range oxazolidinones prepared by this method. Subsequently, a copper-catalyzed diamine developed generate dioxazolidinone. Finally, optimised conditions, we report first time facile synthetic route synthesis polyoxazolidinone, new polyurethane, via multi-component...
A series of catalysts constituted mixed copper and zinc oxides supported on alumina were prepared by co-precipitation method. The cooper content was in the 10-90 wt.% range. Their catalytic behavior hydrogenation carbon dioxide to methanol investigated at high pressure (up 75 bars). characterized elemental analysis, N2-adsorption, N2O-chemisorptions, X-ray diffraction (XRD). showed a clear activity reaction that could be correlated surface area metallic pressure. CuO/ZnO/Al2O3 catalyst with...
The present study was aimed at converting carbon dioxide (CO 2 ) into value-added products such as methanol, which can provide not only a potential solution for controlling the concentration level in atmosphere but also offer an alternative approach production of renewable energy sources. From this perspective, various hybrid photoelectrocatalysts were synthesized, characterized and used photocathodes photoelectrochemical (PEC) reduction to methanol aqueous medium under visible light...
The IR, UV-visible, 1 H NMR and 13 CNMR spectra of C1 C3 are given below, is a compound unsubstituted on 2' imidazole substituted imidazole.
The catalytic activity of various Keggin polyoxometalate catalysts has been investigated in the gas-phase partial oxidation toluene to produce benzyl alcohol and benzaldehyde. catalyst systems HPMo 12 O 40 , 11 VO FePMo PMo FeO 39 were prepared characterized by FT-IR, UV-visible, SEM, XRD, TGA, cyclic voltammetry. acid/base properties evaluated using decomposition isopropanol. Catalytic studies carried under atmospheric pressure over temperature range 200°C–350°C, carbon dioxide as a mild...
The catalytic dehydrocyclization of n-hexane was studied here for the first time using a number compounds based on H3PMo12O40. described catalysts were prepared by either replacing acidic proton with counter-ions such as ammonium or transition metal cations (NH4+, Fe3+, K+), Mo6+ (Ni3+, Co3+, Mn3+) in polyoxometalate framework, reported earlier. For comparison purposes, known (TBA)7PW11O39 catalyst system used. All reactions conducted at different temperatures range 200 - 450. Keggin...
