STRUCTURE-PERFORMANCE RELATIONSHIP IN THE DESIGN OF Ru/TiO2 CATALYST FOR CO2 METHANATION

摘要

The increasing amount of anthropogenic CO2 is recognized as a main culprit of the global climate change. Among various ways to fix exhausted CO2, such as chemical transformation, microbial CO2 fixation or sequestration, catalytic recycling of CO2 appears as very promising. Especially, hydrogenation of CO2 into CH4, so-called methanation reaction, presents important advantage of direct recycling CH4 into fuel and chemicals. Among the previously investigated methanation catalysts, TiO2 supported Ru receives great attention as an effective catalyst due to its high selectivity towards CH at low temperature.
