摘要： A metal/α-MoC1-x load-type single-atomic dispersion catalyst, a synthesis method therefor, and applications thereof. The catalyst uses α-MoC1-x as carrier, and has metal that has the mass fraction ranging from 1-100% and that is dispersed on carrier α-MoC1-x in the single atom form. The catalyst provided in the present application can be adapted to a wide alcohol/water proportion in hydrogen production based on aqueous-phase reforming of alcohols, outstanding hydrogen production performance can be obtained at a variety of proportions, and catalysis performance of the catalyst is much higher than that of metal loaded with an oxide carrier. Especially when the metal is Pt, catalysis performance of the catalyst provided in the present application in the hydrogen production based on aqueous-phase reforming of alcohols is much higher than that of a Pt/α-MoC1-x load-type catalyst on the α-MoC1-x carrier on which Pt is disposed on a layer form in the prior art. The hydrogen production performance of the catalyst provided in the present application can be higher than 20,000 h−1 at the temperature of 190° C.
