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) surfacereveal 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 →

New insights into mercury removal mechanism on CeO

Ling Li, Yu He, Xia Lu

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 2, doi: 10.1007/s11783-018-1007-1

Abstract: First-principles calculations were performed to investigate the mechanism of Hg adsorption and oxidationSurface oxygen activated by the reduction of Ce to Ce was vital to Hg adsorption and oxidation processesHg was fully oxidized by the surface lattice oxygen on CeO (111), without using any other oxidizingIn contrast, O–H and H–O–H groups formed during HCl adsorption consumed the active surface oxygen andThe consumed surface oxygen was replenished by adding O into the flue gas.
