英文摘要The direct conversion of methane to methanol on [Cu(-O)M](2+) (M = Cu, Ag, Zn, Au) bimetal centers in ZSM-5 zeolite is investigated using periodic density functional theory for the first time. Some conclusions are drawn: (1) methane activation on [Cu(-O)M](2+) (M = Cu, Ag, Zn, Au) in the ZSM-5 zeolite proceeds through radical-like transition states, and the ability for CH4 activation decreases in the sequence [Cu(-O)Ag](2+) > [Cu(-O)Au](2+) > [Cu(-O)Cu](2+) > [Cu(-O)Zn](2+). (2) There are two factors that can dramatically enhance C-H bond activation: a greater spin density and a less negative charge of the -O atom. (3) The angles ?CuOM play a minor role in the reactivity difference among [CuOM](2+)-ZSM-5 (M = Cu, Ag, Zn, Au). Our findings will provide insight into methane activation for designing highly effective catalysts applied in industrial processes.
