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。
The polyaniline doped with phosphomolybdic acid (H3PMo12O40, PMA) was prepared by the solid-state reaction method and characterized by FT-IR, XRD and cyclic voltammogram Polyaniline was characterized. The results showed that phosphomolybdic acid doped with polyaniline maintained its own structural characteristics in both liquid and solid phase methods. Compared with the traditional liquid phase synthesis of phosphomolybdic acid-doped polyaniline, solid-state reaction The polyaniline doped with phosphomolybdic acid has slightly worse crystallization rate and electrical activity. The solid-state reaction of polyaniline doped with phosphomolybdic acid showed better electrocatalytic activity than that of liquid phase in the electrocatalytic oxidation of ascorbic acid (AH2).
