摘要：

Theoretical investigation of CO dissociation energy barrier has been performed using density functional theory (DFT) over MoP (100) plane. CO dissociation energy possesses a high activation barrier 87.19 kcal/mol compared to CO adsorption energy 48.97 kcal/mol on the MoP (100) surface, thus making the CO dissociation process kinetically unfavourable. Pronounced electronic effect of the ligand phosphorous was observed during the bond formation on the surface.
