This paper described the recent research of improving methods of TiO2 photocatalytic oxidation dfficiency,whichinvolved metal ion dopants, attachment of sensitizer, surface chelation, surface ramification, surface deposition of noble metal,lanthanon dopants, coupled semiconductors and electron acceptors to broaden the adsoption bands of the TiO2 semiconductorparticle or retard its electron-hole recombination rate. The applications of photocatalytic oxidation on environmental protectionincluding gas cleanup, water treatment and so on were summarized and assessed. Moreover,the further studies were presented.
