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. Theactivation and conversion of CO2 via heterogeneous catalysis is a process that can be achieved in multifunctional catalytic sites, such as metals, carbides, metal/oxide or metal/carbide interfaces1,2.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 precursor3.Here, we report the obtention and characterization of supported molybdenum oxides inside a nanostructured mesoporous silica (SBA-15, pore size ~ 8nm), and the conversion of those oxides intomolybdenum carbides for catalytic CO2 conversion. The carburized materials were analyzed in CO2 conversion at different temperatures, at atmospheric pressure and at 2.0 MPa.
