Mesoporous silicon carbide material and mfg. method thereof

A powdered mesoporous silicon carbide material with beta crystal form, 3-50 nm of pore size distribution and 60-120 sq.m/g of specific surface area is prepared through dissolving phenolic resin in absolute alcohol or acetone, adding transition metal salt, stirring while adding ethyl (methyl or propyl) silicate and inorganic acid, hydrolysis, adding cross-linking agent, gelatinizing, thermal reactino in argon atmosphere, cooling, high-temp treating, acid washing, water washing, filtering and drying. It has low cost.
