Modification of Al2O3 by activated carbon-supported vanadia catalyst studies for ODH of ethylbenzene in presence of CO2 as a soft oxidant
Alumina-carbon composites with variable Al/C ratios, prepared by sol–gel method, have been used as supports for the preparation of V 2 O 5 catalysts. Deposition of V 2 O 5 (10 weight % V 2 O 5 loading) was achieved by impregnation technique. These synthesized catalysts were characterized by various...
