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 m2/g　and　0.46 cm3/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.　©　2007　Elsevier　B.V.　All　rights　reserved.
