Abstract：

A　novel　photocatalyst　CaSn(OH)6　with　middle-sagged　micro-cube　morphology　was　successfully　synthesized　via　a　facile　sonochemical　method.　The　as-synthesized　sample　was　characterized　by　X-ray　diffraction,　X-ray　photoelectron　spectroscopy,　field　emission　scanning　electron　microscopy,　transmission　electron　microscopy,　UV-vis　diffuse　reflectance　spectroscopy　and　N2　absorption-desorption.　The　photoactivity　of　the　sample　was　evaluated　by　the　degradation　of　benzene　under　UV　irradiation.　The　results　indicated　that　CaSn(OH)6　showed　much　better　photocatalytic　activity　and　stability　than　that　of　TiO2　(P25,　Degussa　Co.)　under　the　same　conditions.　CaSn(OH)6　also　exhibited　high　activity　for　methyl　orange　photodegradation.　Additionally,　a　possible　mechanism　of　the　photocatalysis　over　CaSn(OH)6　was　proposed.　©　2011　Elsevier　B.V.　All　rights　reserved.
