Abstract

Catalytic combustion of toluene was investigated on $CuOx/SnO_2-ZrO_2\;CuOx/SnO_2\;CuOx/ZrO_2$ catalysts prepared by impregnation. Characteristics of catalysts loaded on binary support and single support were observed by TPR, TPO, XRD, XPS techniques. The results on catalytic combustion showed that binary supports improve the activity of copper in the combustion of toluene. The reason for high catalytic activity on toluene combustion of $CuOx/SnO_2-ZrO_2$ catalyst was ascribed to oxidation$\cdot$reduction activity at low temperatures and stability of oxidation state after reduction.
