以钨酸钠和盐酸为原料,柠檬酸、酒石酸、对硝基苯甲酸、对氨基苯甲酸和尿素为辅助试剂,在一定温度下通过水热法制备出不同形貌的纳米三氧化钨。对所得产物进行X射线衍射(XRD)、透射电镜(TEM)和扫描电镜(SEM)的分析。结果表明:使用不同的助剂将制备不同形貌的纳米三氧化钨,推测可溶性有机酸在水热反应中起到“软模板剂”的作用,尿素在高压下产生的气体有助于增强产物的分散性,得到尺寸均匀的纳米粉体。
Using sodium tungstate and hydrochloric acid as raw materials,citric acid,tartaric acid,p-nitrobenzoic acid,p-aminobenzoic acid and urea as auxiliary reagents,nano-tungsten trioxides(WO3) with different morphologies were prepared by hydrothermal method at a certain temperature.The obtained product was charactered through X-ray diffraction(XRD),transmission electron microscopy(TEM) and scanning electron microscopy(SEM) analysis.The results showed that the use of different additives will produce nano-WO3 with different morphologies.The soluble organic acid acted as “soft template” in the thermal reactions was speculated,and the gas generated by urea under high pressure helped to enhance the dispersibility of the product,and obtained nano powder with uniform size.
