Abstract

A process for carrying TiO2 photocatalyst on metal surface includes such steps as cleaning metal surface, anodizing in acidic medium, hydrolyzing, leaching and coating tetrabutyl titanate and TiO2 film under the weak alkaline condition by the sol-gel-powder suspension method, and igniting at proper temp. Its advantages are strong photocatalysis action for degradating organic pollutants, and good electric conductivity and machinability.

Description

technical field

[0001] The invention relates to a chemical method for loading titanium dioxide photocatalyst on the metal surface, which can make the metal surface wall and titanium dioxide into an integrated photo(electric) catalyst. It belongs to the field of environmental pollution control technology and the field of new energy research. Metal-supported titanium dioxide can be used as a photocatalyst for degrading organic pollutants, and can also be used as an anode material for photocatalytic reactions. Experimental device materials for solar photolysis of water to produce hydrogen fuel, etc. Background technique

[0002] Photocatalytic materials represented by titanium dioxide have been extensively studied after the discovery of the phenomenon of continuous redox reaction on the surface of titanium dioxide after being irradiated by light. Studies in recent years have shown that the photocatalysis of titanium dioxide has attractive application prospects in solar energy...
