Photoactive catalyst of barium phosphate or calcium phosphate supported on anatase titanium dioxide

摘要

Provided are novel titania comprising anatase titanium dioxide and sodium, potassium, calcium, magnesium, barium, zinc, or magnesium salts of sulfuric or phosphoric acid. The titania of this invention are useful in the pigmentation of oxidizable polymers, while at the same time providing a catalyst system for the photooxidation of said oxidizable polymers.
