摘要: WO3 catalytic powders were successfully synthesized from tungstic acid and sodium tungstate precursors by simple, low-cost sol–gel precipitation methods followed low-temperature hydrothermal treatment. crystallization process was completed with calcination of the samples at 500 700 °C. The effects synthesis method temperature on structural, morphological characteristics surface area investigated. photocatalytic activity evaluated discoloration efficiency methylene blue (MB) aqueous solutions under NUV/visible light irradiation various reaction pH values. MB found to increase increasing pH, best results obtained 9.
