Study on the catalytic activity of vanadium doped TiO2: Anatase-to-rutile phase transition

详细

The catalytic activity of vanadium doped TiO₂ in the ethylbenzene oxidative dehydrogenation with CO₂ was studied experimentally and theoretically. The experimental results showed that the reduction of ethylbenzene conversion and the styrene selectivity was caused by the transition of anatase to rutile phase. Theoretical results showed that the transition of the anatase to rutile phase was mainly caused by vanadium ions and oxygen vacancies.
