Mechanism of methanol decomposition on the Pd/WC(0001) surface unveiled by first-principles calculations

Jinhua Zhang, Yuanbin She

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 6,   Pages 1052-1064 doi: 10.1007/s11705-019-1908-y

Abstract: study, the decomposition of methanol into the CO and H species on the Pd/tungsten carbide (WC)(0001) surfaceis systematically investigated using periodic density functional theory (DFT) calculations.reveal that saturated molecules, i.e., methanol and formaldehyde, adsorb weakly on the Pd/WC(0001) surfaceHowever, most of the other intermediates tend to adsorb to the surface with the carbon and oxygen atomsThus, the most probable methanol decomposition pathway on the Pd/WC(0001) surface is CH OH → CH OH →
