“…[1][2][3] Currently, photocatalytically active semiconductors with good prospects are TiO 2 , SrTiO 3 and ZnO due to their outstanding properties, including chemical stability, strong oxidizing activity, corrosion resistance, and nontoxicity. [7][8][9] Many studies, including experimental results and theoretical calculations, have demonstrated that the heterojunction formed by TiO 2 and modied metal oxides contributes to the efficient separation of photo-generated electron-hole pairs, which prolong the lifetime of excited electrons and holes. Therefore, for practical applications, many methods have been developed for SrTiO 3 modication: noble metal deposition, metal or nonmetal ion doping, sensitization with organic polymers, and coupling with the other semiconductors.…”
