Abstract：

Cube-shaped　hydroxide　ZnSn(OH)6　(ZHS)　has　been　synthesized　by　a　solvothermal　process.　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),　and　Fourier　transformation　infrared　spectroscopy　(FTIR).　Compared　with　commercial　TiO2　(Degussa　P25),　the　as-prepared　ZHS　showed　much　higher　conversion　and　mineralization　of　benzene　under　254　nm　UV　irradiation,　and　no　obvious　deactivation　was　observed　during　the　prolonged　operation　of　50　h.　The　reasons　for　the　high　activity　and　long-term　stability　of　ZHS　will　be　discussed　in　terms　of　the　population　and　the　regeneration　of　surface　OH　groups.　©　2009　Elsevier　B.V.　All　rights　reserved.
