Tungsten Oxide Modified Titanium Dioxide Nanotube Preparation Method
TiO2 photocatalyst due to its excellent photocatalytic performance which has the advantages of light corrosion and chemical corrosion, non-toxic and of low cost has become a topic for many scholars. Titanium dioxide powder is frequently studied at present, however, powder photocatalyst used in water treatment usually require power to maintain the suspension. It was stirred with another catalyst separation and recovery of difficult practical application is limited. Anodic oxidation method for the manufacture of titanium substrate surface titania nanotube array films not only solve the problem of catalyst separation and recovery, and its special tubular structure can provide access to electronic transmission, reducing the composite photo-generated electrons and holes to a certain extent, help improve the efficiency of photocatalytic reaction. A method for the preparation of the tungsten oxide modified titanium dioxide nanotube comprising the steps of: (1)Wash the titanium sh...
