Abstract
The invention relates to a method for preparing a nonmetal-doped TiO2 photocatalyst, comprising the steps of sol-gel, low-temperature burning and heat treatment so as to prepare the nonmetal-doped TiO2 photocatalyst, wherein butyl titanate serves as a former body; a combustion agent is an organic matter or an inorganic matter containing elements needing to be doped; no metal ion is contained in the combustion agent; and no chemical reaction occurs between the incendiary agent and a Ti chemical compound in the combustion process. In the invention, on the basis of studying the preparation of a superfine photocatalyst, the nonmetal-doped TiO2 photocatalyst is prepared through taking the butyl titanate as the former body and choosing a combustion system different from ammonium nitrate, wherein the nonmetal comprises N, P, S, Si, C and the like; and the prepared catalyst has a certain visible light response performance.
