A Comparative Study of Aromatization Catalysts: The Advantage of Hybrid Oxy/Carbides and Platinum-Catalysts Based on Carbon Gels

This manuscript is focused on the relationship between sol-gel synthesis processes and development of new active phases with fitted morphology, porosity surface chemistry. The influence above parameters catalytic performance prepared materials for aromatization n-hexane to benzene also evaluated. Different series catalysts were prepared, either using noble metals (i.e., Pt) or metal oxides Mo, W), as phases. In both cases, stability classical was significantly improved. Interesting one-pot carboreduction process oxide during carbonization suggested a real alternative preparation high-performance catalysts, leading formation less acidic non-stoichiometric carbides.
