Abstract

Potassium carbonate dispersed over a defective TiO2support (K2CO3/TiO2) is an efficient catalyst for benzene esterification with CO2and CH3OH. Density functional theory calculations reveal that this unique catalytic reactivity originates from the cooperation of the Ti3+/K+surface sites. The K2CO3promotor steers the stabilization of surface intermediates thus preventing catalyst deactivation.
