Abstract
A photodegradation catalyst or a photodegradation catalyst precursor comprises a plurality of domains of an oxide of a first metal distributed in a substrate of a halide or oxyhalide of a second metal, wherein the mole percentage of the halide or oxyhalide of the second metal is above 50%. Additionally, a method of preparing a photodegradation catalyst or a photodegradation catalyst precursor, a photodegradation catalyst or a photodegradation catalyst precursor obtained from the method and a method of treating organic pollutants or substances in air or water by using the photodegradation catalyst or the photodegradation catalyst precursor are illustrated.
