Zinc　phthalocyanine　(ZnPc)/ZnO　and　zinc　tetrasulfonated　phthalocyanine　(ZnTSPc)/ZnO　were　synthesized　by　an　in　situ　process.　The　products　were　characterized　by　XRD,　UV-Vis,　FTIR,　and　Fluorescence　spectroscopy　techniques.　The　results　show　that　ZnPc,　ZnTSPc　are　synthesized　on　the　surface　of　ZnO　particles　during　the　in-situ　process.　The　changes　of　fluorescence　intensity　and　lifetime　indicate　that　there　is　no　electron　transfer　between　ZnPc　and　ZnO　while　the　electrons　of　the　excited　state　of　ZnTSPc　are　easily　injected　into　the　ZnO　conduction　band　by　means　of　sulfonated　group　(-SO3-Zn),　and　the　rapid　electron　transfer　rate　of　k(et).,　between　ZnTSPc　and　ZnO　is　equal　to　6.1　x　10(7)　s(-1)　in　1.0mol%　(ZnTSPc:ZnO　in　mol)　ZnTSPc/ZnO.　Compared　with　pure　ZnO,　ZnPc/ZnO　shows　high　photocatalytic　activity　for　the　photocatalytic　decolorization　of　RhB　under　visible-light　irradiation　by　transferring　energy　from　ZnPc　to　oxygen　molecule　and　forming　O-1(2),　while　ZnTSPc/ZnO　reveals　higher　photocatalytic　activity　due　to　O-1(2)　formed　by　means　of　transferring　energy　from　ZnTSPc　to　oxygen　molecule　and　O-2(-)　formed　by　transferring　electron　from　ZnTSPc　to　ZnO.
