以(NH(4))(6)Mo(7)O(24)中心点4H(2)O进行离子交换得到的聚苯胺与三氧化钼(MoO(3))干凝胶的杂化材料，通过过二硫酸铵/HCl氧化剂体系聚合单体合成。通过热重分析、X射线衍射、扫描电子显微镜、充放电测试、循环伏安法、电化学阻抗谱和气敏实验研究了MoO(3)和杂化材料的性能。结果表明，杂化材料比MoO(3)干凝胶表现出更高的容量、更优异的循环可逆性以及对乙醇气体更好的敏感性。
Hybrid material of polyaniline with molybdenum trioxide (MoO (3) ) xerogel obtained by ion exchange of (NH (4) ) (6) Mo (7) O (24) center dot 4H (2) O was synthesized via polymerization of the monomer by ammonium peroxydisulfate/HCl oxidant system. The properties of MoO (3) and hybrid material were investigated through thermogravimetry, X-ray diffraction, scanning electron microscopy, charge-discharge test, cyclic voltammetry, electrochemical impedance spectroscopy, and gas sensing experiments. Results show that hybrid material exhibits higher capacity, more excellent cycling reversibility, and better sensitivity to ethanol gas than MoO (3) xerogel.
