以六氯化钨为原料,以乙二醇、尿素为辅助剂,在酸性反应体系通过醇热法合成了纳米氧化钨。利用XRD、SEM对产物进行了表征,结果表明:控制乙二醇及尿素的加入量,可获得不同形貌的纳米氧化钨。对不同条件下合成的WO3进行紫外可见光光谱分析可知,当反应体系加入乙二醇和尿素,纳米氧化钨的紫外吸收不同程度的减弱,单独加入乙二醇吸收峰发生蓝移,两者同时加入时吸收峰也发生蓝移。 Using tungsten hexachloride as raw material, ethylene glycol and urea as adjuvants, nanometer tungsten oxide was synthesized by alcohol thermal method in acidic reaction system. The products were characterized by XRD and SEM. The results showed that nano-tungsten oxide with different morphologies could be obtained by controlling the amount of ethylene glycol and urea. UV spectroscopy analysis of WO3 synthesized under different conditions shows that when ethylene glycol and urea are added into the reaction system, the ultraviolet absorption of nano-tungsten oxide is weakened to different extents, and the absorption peak of ethylene glycol alone is blue-shifted. When the two are simultaneously added Absorption peak blue shift also occurred.
