Prospects for the Development of Nanocomposite Catalysts for the Oxidative Conversion of C1-C4 Alkanes with Carbon Dioxide to Produce Hydrogen/Synthesis Gas and Organic Compounds: A Review

The ways of targeted design of effective nanocomposite catalysts based on metal oxide systems and zeolites, in particular BEA type, for the processes of dry/super-dry conversion of methane/biogas for the obtaining of hydrogen and syngas with adjustable H₂/CO ratio as well as oxidative dehydrogenation of C₃-C₄ alkanes with the participation of CO₂ producing valuable olefins and dienes are considered. Isolated metal cations/small clusters exhibit higher activity, selectivity, and stability when compared to bulk structures in alkane dehydrogenation reactions since their activation involves the participation of coordinatively unsaturated metal cations on anionic vacancies. This can serve as a scientific basis for the targeted development of highly active and stable catalysts for such processes.
