The catalytic combustion of benzene over SBA-15-supported copper oxide has been investigated. The SBA-15-supported copper oxide catalysts have been prepared by the precipitation-deposition method, and characterized by XRD, BET and TPR. In the CuO/SBA-15 catalysts, the catalytic activity increases with increasing copper oxide loading ratio. Metallic Cu is much more active than copper oxides. When the reduction temperature increases to 500°C the benzene conversion increases until the maximum vlaue is obtained. Further increase in the reduction temperature to 600°C results in a decrease of benzene conversion.
