Molybdenum carbide supported metal catalysts (Mn/MoxC; M = Co, Ni, Cu, Pd, Pt) – metal and surface dependent structure and stability

The surface and metal-dependent morphologies and energies of molybdenum carbide supported metal catalysts (M_n/Mo_xC; M = Co, Ni, Cu, Pd, Pt) have been systematically investigated on the basis of periodic density functional theory computations.

Suppression of platinum sintering on Pt–M/ZSM-22 (M = Ce, La, and Re) catalyst for n-dodecane isomerization

Ce-modified Pt/ZSM-22 catalyst with slightly increased acidity and electron-deficient Pt exhibits improved isomer selectivity and sintering resistance of Pt in n-dodecane isomerization.

Suppression by Pt of CO adsorption and dissociation and methane formation on Fe5C2(100) surfaces

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.

Insight into the structure and morphology of Run clusters on Co(111) and Co(311) surfaces

The adsorption configurations, growth modes and morphology of a Ru promoter under the approximate conditions of cobalt catalyzed Fischer–Tropsch synthesis (FTS) were investigated by density functional theory (DFT) calculations.
