摘要
MoO_(3)具有光催化、电致变色、光致变色以及气敏等特性,在超级电容器电极材料、气敏材料、光催化材料、阻燃抑烟等领域具有广泛运用,研究发现溶液热解法在调控MoO_(3)粉体颗粒结构和尺寸、提升其应用性能方面具有明显优势。以仲钼酸铵(七钼酸铵)为原料,通过改变温度条件、pH、表面活性剂等工艺参数,获得了具有丰富物相和形貌结构的MoO_(3)粉体。利用X射线衍射仪(XRD),扫描电子显微镜(SEM)对材料的物相和形貌进行了表征,并对影响颗粒形成的关键因素和过程机理进行了探讨。
Molybdenum trioxide(MoO_(3))has the characteristics of photocatalysis,electrochromism,photochromism and gas sensitivity,and is widely used in the fields of supercapacitor electrode materials,gas-sensitive materials,photocatalytic materials,flame retardant and smoke suppression.Researches have found that the solution pyrolysis method has significant advantages in regulating the particle structure and size of MoO_(3) powder and improving its application performance.Using ammonium paramolybdate(ammonium heptamolybdate)as raw material,MoO_(3) powder with rich phase and morphological structure was obtained by changing the temperature conditions,pH value,.surfactant and other process parameters.X-ray diffraction(XRD)and scanning electron microscopy(SEM)were used to characterize the phase and morphology of the material,and the key factors affecting particle formation and process mechanisms were discussed.
