To understand the chemical origin of platinum promotion effects on iron based Fischer–Tropsch synthesis catalysts, the effects of Pt on CO adsorption and dissociation as well as surface carbon hydrogenation on the Fe5C2(100) facet with different surface C* contents have been studied using the spin-polarized density functional theory method.

Metal Support Interactions

The SMSI between Fe and oxygen vacancies in Ce0.8Sm0.2O2−δ helps to weaken and break the strong NN bonds in N2, increasing the catalytic activity. Materials with anion vacancies improve oxygenate tolerance property of ammonia synthesis catalysts.
