Abstract：

Copper　tetrasulfonated　phthalocyanine　(CuTSPc)-sensitized　mesoporous　SnO2,　namely　CuTSPc/SnO2,　was　prepared　by　a　simple　template-free　hydrothermal　method.　X-ray　diffraction,　transmission　electron　microscopy,　N2　adsorption-desorption,　Fourier　transform　infrared　spectroscopy,　and　UV-Vis　spectroscopy　were　used　to　characterize　the　samples.　The　photocatalytic　activity　and　circulating　degradation　rate　of　the　photocatalysts　under　low-power　visible　light　(15　W)　were　determined　using　rhodamine　B　(RhB)　as　the　objective　decomposition　substance.　It　was　found　that　the　sulfonated　groups　of　CuTSPc　are　bonded　to　the　tin　ion　in　a　chelating　bidentate　mode　in　CuTSPc/SnO2,　and　the　specific　surface　area　and　pore　size　for　0.1　mol%CuTSPc/SnO2　are　236　m2/g　and　2.6　nm,　respectively.　The　degradation　rate　of　RhB　with　0.1　mol%　CuTSPc/SnO2　is　up　to　87%　during　180　min　of　reaction.
