In this study, Ni/SiO2 catalysts promoted by Fe, Co and Zn were prepared by simple wet impregnation and evaluated in the CO2 conversion to methane. The samples were characterized by TGA-DTA, XRD, N2 physisorption, H2-TPR and TPO-DTA. The reactions were carried out at 1 atm in a fixed...

which was triggered when methane production rates were low. Since methylotrophic methanogenesis rates are much lower in marine sediments than under optimal conditions in pure culture, CO2conversion to methane is an important but previously overlooked methanogenic process in sediments...

to improved CO2 conversion.As a result,an effective synergy between the active Ni sites and surface oxygen vacancies on In2O3 causes a superior catalytic performance for CO2 hydrogenation with high methanol selectivity.Carbon monoxide is the only by product detected.The formation of methane can be...
product in the early stage of the reaction, at higher conversion both methylformate (the product of a Tishchenko-like dimerization of formaldehyde) and dimethoxymethane (formaldehyde dimethyl acetal) could eventually be detected in solution. No carbon monoxide or methane contaminants were detected in ...
Conversion of Methane to Methanol at the Mononuclear and Dinuclear Copper Sites of Particulate Methane Monooxygenase (pMMO): A DFT and QM/MM Study. Methane hydroxylation at the mononuclear and dinuclear copper sites of pMMO is discussed using quantum mechanical and QM/MM calculations. Possible mecha...
Electrochemical conversion of CO2 into value-added chemicals holds promise to enable the transition to carbon neutrality. Enhancing selectivity for a specific hydrocarbon product is challenging, however, due to numerous possible reaction pathways of CO2 electroreduction. Here we present a Cu–polyamine hyb...
