Abstract: The invention provides a photocatalytic structure comprising a carrier and a photocatalytic film formed on the carrier, in which the photocatalytic film comprises titanium dioxide with shape of rhombus particles. The titanium dioxide particle has anatase structure. The titanium dioxide particle is rhombus with a major axis 10-15 nm and minor axis 3-6 nm. The photocatalytic film which is formed by titanium dioxide with shape of rhombus particles has a high overall photocatalytic activity so that the effects of stainproofing and self-cleaning can be improved. The invention also relates to a method for manufacturing photocatalytic sol-gels.
