Effect of thermal treatment on various characteristics of undoped and V sub 2 O sub 5 -doped Co sub 3 O sub 4 /TiO sub 2 catalysts

Thermal treatment of the catalysts was studied at 330- 600 degrees C in vacuum and in air. The wide difference in the catalytic behavior of the two catalysts could be attributed to surface as well as bulk diffusion of the active CoO particles. Bulk diffusion enhanced by doping might cause some modif...

Description
Summary:Thermal treatment of the catalysts was studied at 330- 600 degrees C in vacuum and in air. The wide difference in the catalytic behavior of the two catalysts could be attributed to surface as well as bulk diffusion of the active CoO particles. Bulk diffusion enhanced by doping might cause some modification in the porosity characteristics of the TiO sub 2 support. 46 refs.
