To　fabricate　the　H2-O2　promoting　effect　systems　for　quicker　degradation　of　organic　pollutants　without　an　external　H2　supply,　we　replace　pure　Pt/TiO2　photocatalyst　by　a　cooperative　catalyst　composed　of　Pt/TiO2　and　some　assistant　catalysts　with　water-splitting　ability.　When　the　cooperative　catalysts　were　used　for　the　photooxidation　of　organic　pollutants　under　UV　light　irradiation,　enhanced　activities　were　observed　for　salicylic　acid　and　phenol　removal,　except　for　formate,　as　compared　to　pure　Pt/TiO2　catalyst.　For　different　metal　oxides　as　the　assistant　catalyst,　an　increase　in　the　activity　depended　on　their　ability　to　promote　H2　release.　The　fluorescence　spectroscopy　and　photometric　techniques　combind　with　GC-MS　were　applied　to　investigate　the　cooperative　system.　Results　revealed　that　more　hydroxyl　radical　(O　2H2)　and　hydrogen　peroxide　(H2O2)　were　formed　from　the　H2O　molecules　over　a　cooperative　catalyst.　A　photodegradation　mechanism　of　organic　pollutants　on　a　cooperative　catalyst　is　proposed.　©　2010　Elsevier　B.V.　All　rights　reserved.
