The chemical transformation of CO2 is an alternative to convert a greenhouse gas extensively emitted to the atmosphere in the combustion of fossil fuels combustion into chemicals and fuels. The activation and conversion of CO2 via heterogeneous catalysis is a process that can be achieve in multifunctional catalytic sites, such as metals, carbides. metal/oxide or metal/carbide interfaces. In addition, the carburization of transition metals, such as molybdenum, has shown to be dependent of the particle size and the molybdenum oxides used as precursor.Here, we report the obtaining and characterization of supported molybdenum oxides inside a nanostructured mesoporous silica (SBA-15, pore size 8nm), and the conversion of those oxides into molybdenum carbides for catalytic CO2 conversion. The carburized materials were analyzed in CO2 conversion at different temperatures, at atmospheric pressure and at 2,0 MPa.
