摘要：
There are disclosed a catalyst which comprises a carrier composed of a porous silicon carbide or a porous silicon nitride prepared by a silicon-accumulated biomass and a catalytic substance supported thereon, and a method for preparing a catalyst which comprises supporting a catalytic substance on a porous silicon carbide or a porous silicon nitride prepared by subjecting a silicon-accumulated biomass to heat treatment under an argon or a nitrogen atmosphere.
