Abstract

The dehydration of 1-propanol on nanoporous WO ₃ films prepared via ballistic deposition at ∼20 K has been investigated using temperature-programmed desorption, infrared reflection absorption spectroscopy, and density functional theory. The as-deposited films are extremely efficient in 1-propanol dehydration to propene. This activity is correlated with the presence of dioxo O=W=O groups, whereas monooxo W=O species are shown to be inactive. Annealing of the films induces densification that results in the loss of catalytic activity due to the annihilation of O=W=O species.
