摘要
A TiO2-capsulated metallic nano particles type photocatalyst and a preparation method thereof are provided to replace imported TiO2 photocatalysts and improve residential environment by environmental purification effects. A TiO2-capsulated metallic nano particles type photocatalyst comprises a core metal nano particle and a TiO2 coating layer on the core metal nano particle. The core metal nano particle has a particle diameter of 1~100nm. The TiO2 coating layer has the thickness of 1~100nm. The core metal nano particle comprises one or more metals selected among Au, Ag, Pt, Pd, Cu, Ni, Co, Fe, ZnO, SiO2, ZrO and Al2O3. A method for producing the TiO2-capsulated metallic nano particles type photocatalyst includes the following steps of: mixing a complex salt diluting solution of titanium alkoxide to a metal nano particle colloidal solution; hydrothermally synthesizing the mixed solution; and coating the metal nano particle with TiO2.
