【摘要】 利用固相反应法制备了磷钼酸(H3PMo12O40,简称PMA)掺杂聚苯胺,并以红外光谱(FT-IR)、X-射线衍射(XRD)、循环伏安(cyclic voltamm ogram)等测试方法对聚苯胺进行了表征。结果表明,无论是液相法还是固相法,磷钼酸掺杂于聚苯胺中,仍保持自身结构特征,与传统液相合成的磷钼酸掺杂聚苯胺相比,固相反应法合成的磷钼酸掺杂聚苯胺的晶化率和电活性略差。固相反应法制备的磷钼酸掺杂聚苯胺在对抗坏血酸(AH2)电催化氧化中,表现出比液相合成更好的电催化活性。更多还原

【Abstract】 Polyaniline doped with H3PMo12O40 was prepared by solid-state polymerization method and characterized by FT-IR,SEM,XRD and cyclic voltammogram,respectively.The effect of solid-state polymerization of polyaniline doped with H3PMo12O40 on its electrocatalysis activity was also discussed.Results showed that polyaniline doped with H3PMo12O40 prepared by solid-state polymerization method had good order and crystallinity,and displayed good electrochemical stability.On the contrary,polyaniline doped with H3PMo12O40 prepared by solid-state polymerization method had higher electrocatalysis activity than that of polyaniline doped with H3PMo12O40 prepared by liquid phase polymerization method.更多还原
