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
