報告摘要：
In the early studies of heterogeneous catalytic applications of transition metal carbides (TMCs), the carbide itself was used individually as the catalytic active site which exhibited unique catalytic performance comparable to precious metal catalysts towards hydrogenation, dehydrogenation, isomerization, and hydrodeoxygenation. To promote the catalytic performance, the doping of secondary transition metals into the carbide lattice to form bimetallic carbides was extensively studied. In a third approach, TMCs could be used with noble metal or other transition metals, constituting the bifunctional or interfacial catalyst system. Indeed, due to its unique nature of chemical structures and electronic properties, molybdenum carbide has exhibited tremendous advantages as a promising catalyst and support for metal catalysts, leading to improved activity, selectivity and stability of catalysts. In this talk, recent progress has been reviewed for the preparation and rational design of molybdenum carbide-based catalysts towards reactions such as hydrogen production and purification, CO-resistant hydrogenation and tandem bifunctional conversion of CO+H2O in biomass conversion and FTS. The understandings toward the structure-performance relationship in molybdenum carbide and molybdenum carbide supported catalysts are also addressed.
