【摘要】以有机混合物为溶剂,采用溶剂热法制备W18O49催化剂,对催化剂进行XRD、N2吸附-脱附、紫外可见漫反射和热重等表征分析,并将催化剂用于光催化降解次甲基蓝。结果表明,W18O49催化剂对次甲基蓝可见光降解有很好的催化作用,室温光照180 min时,降解率达95.9%。更多还原

【Abstract】 W₁₈O₄₉ catalysts were synthesized by solvo thermal method inorganic mixed solvent characterized by X-ray diffraction,N2 adsorption-desorption isotherms analysis,UV-visiblediffusereflectance spectra,thermogravimetric analysis techniques. The W18 O49 catalysts show excellent photo catalytic activity in the photodegradation of MB under visible light,the degradation efficiency of MB reaches 95. 9% within180 min of irradiation at room temperature.更多还原
