Interesting influence of AlO on the catalytic stability of CoP, MoP and CoMoP catalysts for dry reforming of methane.

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 AlO, there was a rise, decline and no change in the catalytic stability of CoMoP, MoP and CoP, 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.
