- Abstract
Utilization of CO as a soft oxidant in the oxidative dehydrogenation of ethylbenzene to styrene, a remarkable VO-SbO-CeO/TiO-ZrO catalyst has been accomplished. Preparation of TiO-ZrO support by co-precipitation followed by a single step deposition of V and Ce and Sb as stabilizers yielded a highly active and selective catalyst. Acid-base and redox properties including sustained stability of active species (V) are responsible for high activity of VO-SbO-CeO/TiO-ZrO catalyst. The redox cycle is related to the dispersed V and lattice reduced vanadium site in the VSbO phase. The antimony oxide inhibits the easy redox cycle between different vanadia species.
