Visible ray reaction type photocatalyst and preparation method thereof

摘要

PURPOSE: A visible light sensitive titanium dioxide photocatalyst and a manufacturing method thereof are provided to be sensitive to visible rays, and to have a small and regular particle size by containing indium and vanadium. CONSTITUTION: A visible light sensitive titanium dioxide photocatalyst includes indium and vanadium. The combination ratio of titanium, indium, and vanadium is 10-60 parts by weight:1-3 parts by weight:0.5-1.5 parts by weight. A manufacturing method of the visible light sensitive titanium dioxide photocatalyst comprises the following steps: Indium and vanadium are mixed to manufacture an aqueous solution. Titanium and polyethylene glycol are mixed to manufacture a mixed solution. The aqueous solution and the mixed solution are mixed to obtain a reacting solution. Titanium in the reacting solution is oxidized through a thermal process to obtain titanium dioxide.
