A series of dual copper-cobalt oxides-containing mesoporous molecular sieve catalysts xCuyCo/NS-MS-s were successfully fabricated by an improved micelle-assisted synthetic method. Taking gaseous toluene as the representative pollutant of VOCs, the removal effect of toluene by the catalysts was investigated. The physicochemical properties including structure, the morphology of catalysts, and the chemical status of Cu-Co bimetallic species were detailedly identified through various characterizations. The results showed that when the ratio of bimetal was controlled as n_Cu: n_Co=1:3, the catalyst had the best catalytic combustion activity of toluene (T₅₀=232 ℃, T₉₉=239 ℃, where T₅₀ is the reaction temperature when the toluene conversion is 50%, and T₉₉ is the reaction temperature when the toluene conversion is 99%) and good stability.
