Abstract：

Nanocrystalline　Sr2Sb2O7　with　small　particles　and　a　large　BET　specific　area　was　prepared　successfully　via　a　facile　hydrothermal　method　from　Sb2Os.　The　obtained　sample　was　characterized　by　X-ray　diffraction　(XRD),　N2-sorption　BET　surface　area,　UV-vis　diffuse　reflectance　spectroscopy　(DRS),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　high-resolution　transmission　electron　microscopy　(HRTEM),　and　Fourier　transformation　infrared　spectroscopy　(FT-IR).　The　as-prepared　Sr2Sb2O7　showed　high　photocatalytic　activity　for　benzene　degradation　under　254　nm　UV　irradiations,　and　no　deactivation　was　observed　during　the　prolonged　photocatalytic　reaction.　The　photocatalytic　performance　of　the　hydrothermal　synthesized　Sr　2Sb2O7　was　superior　to　both　P25　and　Sr　2Sb2O7　prepared　by　the　conventional　solid-state　reaction.　A　possible　mechanism　of　the　photocatalysis　over　Sr2Sb　2O7　was　also　proposed.　©　2008　American　Chemical　Society.
