Photocatalytic titanium dioxide powder, process for producing same, and applications thereof |
摘要 |
A photocatalytic powder comprising finely divided titanium dioxide particles having a coating of a substantially water-insoluble organic substance on the surface of each titanium dioxide particle. The photocatalytic powder is made by adding an insolubilizer to a slurry containing finely divided titanium dioxide particles and a water-soluble organic substance to form a coating of an substantially water-insoluble organic substance on the surface of each titanium dioxide particle. The photocatalytic powder is used in the form of a mixture with an organic polymer for making a shaped article having good environmental clarifying property, or is supported on the surface of a structure to provide a structure having good environmental clarifying property.
