Abstract

A monolithic Cu-Mn-Ce oxides supported on a ring of silicon carbide (SiC) with molar ratios 1:2:1 were prepared by the sol-gel combustion method without any binder. The catalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller method (BET). Toluene was chosen as a model compound to evaluate the catalytic activity in a conventional fix-bed quartz reactor. The results showed that the mixed oxides adhered firmly to the ring of silicon carbide surface. Compared with the conventional heating, the Cu-Mn-Ce oxides monolithic catalysts under microwave irradiation showed higher activity for the combustion of toluene in the low temperature range (350 oC<400 oC) and the 90% of toluene conversion was achieved at 350 oC.
