英文摘要: The catalytic hydrogenation of CO2 to methane has been receiving an increasing attention as a method to mitigate the concentration of CO2 in the atmosphere through the production of synthetic natural gas. Finding the effective catalyst is the key factor to make this process feasible. In the present work, hydrogenation of CO2 into CH4 over novel metal oxide nanocatalysts supported on wire gauzes made from kanthal steel (FeCrAl) has been studied. The series of thin films of active phase were prepared by plasma-enhanced metalorganic chemical vapor deposition (PEMOCVD), containing cobalt spinel (Co3O4), ruthenium oxide (RuO2), mixed oxides (RuO2/Co3O4) and iron oxide (Fe2O3). The activity of the prepared nanocatalysts was tested in the gradientless reactor in the temperature range of 150-500 °C. The RuO2 catalyst revealed the highest both the yield of methane and the reaction rate, while the Fe2O3 catalyst promoted the CO production through reverse water-gas shift reaction. The results of the present studies are the foundation for further research on a new class of nanomaterials with high catalytic properties for the methanation reaction. © 2017 Elsevier Ltd.
