Abstract：

Two　facile　and　green　methods　without　any　templates,　catalysts,　surfactants　or　organic　solvents　were　applied　to　synthesize　ZnSn(OH)　6　nanoparticles,　i.e.　homogeneous　precipitation　(HP)　and　hydrothermal　(HT).　The　photocatalytic　activities　were　evaluated　on　the　degradation　of　organic　pollutants　under　ultraviolet　light　illumination.　Compared　to　commercial　P25,　the　photoactivity　of　ZnSn(OH)　6　was　remarkably　improved.　The　conversion　and　mineralization　ratio　of　the　photocatalytic　degradation　of　benzene　by　the　ZnSn(OH)　6　-HP　were　up　to　75%　and　68%,　which　is　about　20　and　2　times　higher　than　that　of　P25.　The　ZnSn(OH)　6　has　also　exhibited　high　performance　toward　other　persistent　organic　compounds　as　well　as　methyl　orange　in　suspended　solution.　The　order　of　photodegradation　efficiencies　of　different　catalysts　was　ZnSn(OH)　6　-HP>P25>ZnSn(OH)　6　-HT.　Based　on　the　characterization　results　and　the　detection　of　active　species,　the　possible　mechanism　of　the　high　photocatalytic　activity　of　ZnSn(OH)　6　-HP　was　discussed.　The　simplified　synthesis　of　zinc　hydroxystannate　with　outstanding　activity　could　be　promisingly　used　in　the　future　photocatalytic　application.　©　2011　Elsevier　B.V.
