外文摘要：In this investigation, SBA-16 was used to support metal (M = Cr, Mn, Fe, Co, Ni, Cu) oxides and ceria catalysts for the complete oxidation of benzene. The influence of a ceria promoter on the structure of SBA-16 and the catalytic performance of Co/SBA-16 were investigated. Mesoporous SBA-16 was found to have high surface area (472.1 m(2)/g) and large pore volume (0.69 cm(3)/g). The mesoporous, cage-like structure of SBA-16 was maintained throughout the preparation of CoCe supported catalysts. The addition of ceria promoted the reduction of cobalt oxide at a lower temperature and greatly affected its catalytic activity. These effects could be attributed to the good dispersion of Co3O4 on SBA-16 and the strong interaction between Co3O4 and CeO2. Catalysts with appropriate Ce greatly enhanced the activity of Co/SBA-16 for complete benzene oxidation; the catalyst CoCe(18:1)/SBA-16 exhibited the highest activity at 265 degrees C. The high catalytic activity can likely be attributed to the high dispersion of Co3O4 on SBA-16, the high S-BET, and the strong interaction between Co3O4 and CeO2. (C) 2013 Elsevier B.V.
