摘要：

A　facile　one-step　solvothermal　method　was　used　to　synthesize　tungsten　oxides　by　organic　solvents,　namely　ethanol,　n-propanol　and　n-hexane.　Three-dimensional　WO3　nanoflowers,　two-dimensional　WO3　nanoslice　and　zero-dimensional　nonstoichiometric　WO3-x　nanoparticles　were　obtained.　The　growth　mechanism　in　different　organic　solvents　was　proposed,　in　which　the　functions　of　hydroxyl　groups,　solvents　polarity,　and　dissolved　oxygen　were　considered　complementarily.　The　visible-light　driven　photocatalysis　of　these　tungsten　oxide　nanostructures　were　studied　by　photodegradation　of　a　dye　methylene　blue　(MB)　and　an　endocrine　disrupting　compound　bisphenol　A　(BPA)　under　visible　light,　and　all　products　exhibited　a　degradation　rate　up　to　95%,　indicating　their　applicative　potential　in　wastewater　treatment.　The　recycling　property　and　different　parameters　of　pH,　catalyst　concentration　and　dye　concentration　for　the　photodegradation　process　towards　MB　solution　were　also　studied　and　illustrated.　©　2020　Taiwan　Institute　of　Chemical　Engineers
