摘　　要：以仲钼酸铵(AHM)为钼源,以聚乙二醇(PEG)为模板剂,用冰醋酸调节合成液的酸度为2.76,在60℃恒温条件下,生成三氧化钼的前驱体(中间体)。经洗涤、干燥、焙烧,得到淡蓝色或淡绿色粉末。利用扫描电子显微镜观察及X射线衍射分析,生成的粉末为纳米级α-MoO3。通过调节模板剂PEG的分子量、PEG与AHM的质量比、焙烧温度等因素,获得了在制备方面有意义的结果。Molybdenum trioxide precursors （intermediate） are prepared by using Ammonium paramolybdate as molybdenum source, PEG as template agent when the acidity of glacial acetic acid is 2.76 at 60℃. Light blue or light green powder are produced by washing, drying and calcinations. Scanning electron microscopy and X-ray diffraction analysis shows that the powder is the nano-sized α-MoO3.Some significant data are achieved by adjusting the molecular weight of PEG template agent, mass ratio between PEG and AHM and calcination temperatures.
