Abstract：

Orthorhombic　Bi2SiO5　nanosheets　with　thicknesses　of　10-20　nm　were　first　synthesized　by　a　template-free　hydrothermal　synthesis　process　using　Bi(NO3)3　and　different　Si　sources　as　raw　materials.　The　as-prepared　samples　were　characterized　by　X-ray　diffraction,　Brunauer-Emmett-Teller　(BET)　surface　area　analysis,　UV-vls　diffuse　reflectance　spectroscopy,　scanning　electron　microscopy,　high-resolution　transmission　electron　microscopy,　and　a　photoluminescence　technique　with　terephthalic　acid.　The　results　showed　that　different　precursors　led　to　samples　with　different　morphologies,　particle　sizes,　and　BET　surface　areas.　As　a　novel　photocatalyst,　the　photocatalytic　performances　of　Bi2SiO5　samples　were　evaluated　by　the　photocatalytic　degradation　of　salicylic　add　and　gaseous　benzene.　The　results　revealed　that　the　sample　obtained　from　Na　2SiO3　as　a　precursor　exhibited　higher　activity　than　that　from　(C2H5O)4Si　due　to　its　biscuit-like　morphology,　a　smaller　particle　size,　and　a　higher　BET　surface　areas.　©　2009　American　Chemical　Society.
