Mesoporous CuO/CeO2 bimetal oxides: One-pot synthesis, characterization and their application in catalytic destruction of 1,2-dichlorobenzene

Mesoporous CuO/CeO2 bimetal oxides were synthesized by a one-pot method using a cationic surfactant CTAB as structure directing agent and Cu(NO3)2·3H2O, Ce(NO3)·6H2O and NaOH as the inorganic precursor at ambient temperature, and were characterized by XRD, N2 adsorption/desorption, TEM, XPS and TPR techniques. The results revealed that the as-prepared mesoporous CuO/CeO2 bimetal oxides possessed a disorder wormlike porous structure, a high BET surface area and uniform pore-size distribution after calcination at 500 °C. The results of catalytic activity measurements showed that the as-prepared mesoporous CuO/CeO2 bimetal oxides were very active for catalytic oxidative destruction of 1,2-dichlorobenzene, indicating theirs potential application in the removal of chlorinated volatile organic compounds.
