Interesting influence of Al2O3 on the catalytic stability of Co2P, MoP and CoMoP catalysts for dry reforming of methane

Abstract

Interestingly, the metal–support interaction (MSI) influence of different metal phosphides on catalytic stability might be different in dry reforming of methane (DRM). After being supported on Al₂O₃, there was a rise, decline and no change in the catalytic stability of CoMoP, MoP and Co₂P, respectively. This was probably because the MSI can tune the structural stability, methane dissociation ability and oxidation resistance ability of metal phosphides, which were the key factors that determined their catalytic stability.
