Catalytic Removal of Toluene from Air Streams by Cobalt Oxide Supported on Sepiolite

Removal of toluene using cobalt oxide supported on sepiolite catalysts was investigated. Deposition precipitation method was used to prepare the catalysts. The catalysts were characterized using X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric analysis (TGA) and Brunauer-Emmet-Teller methods. The results of catalytic testing showed that 20% cobalt oxide/sepiolite (Co20/Sep) had higher catalytic activity for degradation of toluene. A temperature of 400 ºC was found to be the optimum calcination temperature for Co20/Sep, sin...
