Abstract：

Controlled　assembling　of　Sn　3　O　4　nanoflakes　over　multi-wall　carbon　nanotubes　(CNTs)　was　achieved　for　the　first　time　by　using　a　facile　hydrothermal　method.　The　SEM　and　TEM　images　showed　that　numerous　Sn　3　O　4　nanoflakes　were　widely　assembled　over　the　surface　of　CNTs.　In　these　hybrids,　the　CNTs　served　as　dispersing-template　could　reduce　the　agglomeration　of　Sn　3　O　4　nanoflakes,　as　well　as　facilitate　the　interfacial　charge　transfer　because　of　its　high　electrical　conductivity.　The　Sn　3　O　4　-CNTs　photocatalysts　have　exhibited　remarkably　promoted　performances　in　decomposing　organic　contaminant　under　visible　or　solar　light.　The　Sn　3　O　4　-CNTs　hybrid　with　CNTs　mass　ratio　of　4.37%　exhibited　the　best　activity　under　visible　light,　while　that　with　CNTs　mass　ratio　of　1.41%　was　more　efficient　when　irradiated　by　solar　light,　the　activity　of　which　was　about　3.47　times　higher　than　that　of　pristine　Sn　3　O　4　under　identical　conditions.　Controlled　experiments　proved　that　[rad]O　2　−　and　h　+　played　the　chief　role　in　decomposing　organic　pollutants.　©　2018　Elsevier　Ltd
