Metal / .ALPHA.-MoC1-x-supported single atom dispersion catalyst, synthesis method and use thereof

摘要

Metal / .alpha.-MoC1-x-supported single atom dispersed catalyst, method for synthesizing the same, and application thereof. The catalyst uses α-MoC 1-x as a support, has a weight fraction of 1 to 100% and has the metal dispersed in the form of a single atom on the support α-MoC 1-x. The catalyst provided herein can be adapted to a wide range of alcohol / water ratios in hydrogen generation based on aqueous phase reforming of alcohol, can obtain excellent hydrogen generation performance at various ratios, and The catalytic performance is much higher than the metal supported on the oxide support. The catalytic performance of the catalyst provided herein in hydrogen generation based on aqueous phase reforming of alcohol, especially when the metal is Pt, is the prior art Pt in which Pt is arranged in layers on the α-MoC 1-x support Much higher than the catalytic performance of the / α-MoC 1-x supported catalyst. The hydrogen generation performance of the catalyst provided herein can be higher than 20000 h-1 at a temperature of 190 ° C. [Selected figure] Figure 2
