Catalytic oxidation of CO and o-DCB over CuO/CeO2 catalysts supported on hierarchically porous silica

► Synthesis of the CuO/CeO2 catalysts supported on hierarchically porous silica. ► The resulted materials possess the mesoporous and through-macroporous structure. ► The results of combined catalytic oxidation for CO and o-DCB are first shown. ► Optimally, 100% conversion of CO at 110 °C and 98.8% conversion of o-DCB at 500 °C.
