Method of manufacuring oxidized layer of oxidized titanium for photo-catalyst and Oxidized layer oxidized titanium for photo-catalyst manufactured by the same

摘要

A preparation method of a titanium oxide layer for photocatalyst and a titanium oxide layer for photocatalyst prepared by the preparation method are provided to prepare a titanium oxide layer for photocatalyst having improved photolysis efficiency as a photocatalyst while reducing the production cost by performing a preparation process easily. A preparation method of a titanium oxide layer for photocatalyst comprises the steps of: preparing an aqueous alkaline solution as an electrolyte in an electrolyzer made of metal; dipping a titanium(Ti) metal as an anode into the electrolyte and dipping a stainless steel as a cathode into the electrolyte; and applying a voltage of 320 to 340 V to the anode and the cathode for 10 to 40 minutes to form a titanium oxide layer having a volume ratio of rutile phase to anatase phase of 7 to 11% by volume on a surface of the titanium metal. The electrolyte is an aqueous sodium phosphate(Na2HPO4) solution having a concentration of 20 to 40 g/L. The titanium oxide layer is formed on the surface of the titanium metal by dielectric breakdown.
