摘要： The present invention provides a photocatalytic oxide for car's side mirrors, which is coated on the chrome-coated layer of a front surface mirror to enhance the durability of the front surface mirror and to impart hydrophilicity to the front surface mirror, thus being capable of providing safe visibility for car drivers, as well as a producing method thereof. The producing method of the photocatalytic oxide comprises the steps of: stirring tetraethyl orthosilicate (TEOS) and titanium isopropoxide (TIP) in 2-propanol as a solvent, in which the volume ratio between the tetraethyl orthosilicate (TEOS) and the titanium isopropoxide (TIP) is 50:50, 30-50:40 or 20-40:30 while the amount of the solvent is maintained at a constant; subjecting the stirred mixture to a reaction; washing the reacted material with water/alcohol by centrifugation; separating the water/alcohol; and collecting a hydrophilic coating solution.
