Structural Changes of Mo/ZSM-5 Catalysts During the Methane Dehydroaromatization

Eurasian Chemico-Technological Journal, 2010
The structure changes of Mo/ZSM-5 catalysts with different Mo content (2 and 10 wt. % Mo) and Si/Al atomic ratio (17, 30 and 45) during the methane dehydroaromatization have been investigated by X-ray powder diffractometry, N2 adsorption and ...

Facet‐Dependent Water Inhibition of Alkanol Dehydration on TiO2 via Distinct Water–Alkanol Complexes

Angewandte Chemie, EarlyView.
Water inhibits alkanol dehydration on TiO2 through facet‐dependent manners via distinct IPA‐water complexes. On TiO2(001), water forms a strongly hydrogen‐bonded isopropoxide–H2O complex that readily dominates the surface and substantially elevates the activation barrier, whereas on TiO2(101), water weakly hydrogen‐bonds to molecular IPA, resulting in ...
