Abstract
The catalytic behaviour in the oxidative dehydrogenation of ethane of TiO2- and SiO2-supported catalysts containing bulk-like VOPO4 particles has been compared to that of TiO2-supported highly dispersed VOPO4. The catalysts h ave been characterised by XRD analysis and BET measurements. Redox properti es have been studied by TPR experiments. A correlation of catalytic activit y and C2H4 selectivity with redox properties has been proposed.
