Synthesis of porous SiC and application in the CO oxidation reaction

Porous silicon carbide (SiC) was synthesized by carbothermal reduction method. In this method, the sucrose and the tetarethoxysilane (TEOS) were used as carbon resource and silicon resource. The surface area and pore volume of the obtained SiC was 157 m 2/g and 0.46 cm 3/g, respectively. Then the Pt...

Description
Summary:Porous silicon carbide (SiC) was synthesized by carbothermal reduction method. In this method, the sucrose and the tetarethoxysilane (TEOS) were used as carbon resource and silicon resource. The surface area and pore volume of the obtained SiC was 157 m 2/g and 0.46 cm 3/g, respectively. Then the Pt/SiC was prepared by incipient impregnation method for the CO oxidation. The result shows that the catalyst exhibits relatively high catalyst activity, and makes it likely that SiC will become the subject of intense research as a potential new catalyst support material.
