Abstract
New types of photocatalyst materials are disclosed together with methods for preparing and using these materials, as well as air treatment systems incorporating such materials. The photocatalyst materials of this invention consist essentially of very small particles of a first-metal oxide, the first-metal being a metal that exhibits photo-induced semiconductor properties, having ions of a second-metal dispersed throughout its lattice structure, the second-metal being selected from the group of dopant metals. Such photocatalyst materials are prepared by the steps of mixing first-metal and second-metal precursors, removing nonessential ions from the mixture, drying the resulting product, and calcinating the dried product to produce the completed photocatalyst material.
