离子液体[bmim]HSO_4中合成的苯胺与环氧丙烷共聚物的电催化性能

Electrocatalytic Activity of Polyaniline-Poly(Propylene Oxide) Prepared in Ionic Liquid [bmim]HSO_4

采用恒电流电解法,在1-丁基-3-甲基咪唑硫酸氢盐([bmi m] HSO4)离子液体中合成了苯胺与环氧丙烷共聚物(PAN-PPO) .扫描电镜观察表明,PAN-PPO由直径小于80 nm的纳米纤维组成.PAN-PPO对草酸氧化具有较好的电催化活性.采用电化学原位红外光谱技术对草酸的电催化氧化进行了简单的分析.

Copolymerization of aniline and propylene oxide was carried out galvanostatically in an ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate （[bmim] HSO4）. Scanning electron microscopy shows that the copolymer of polyaniline-poly（propylene oxide） （PAN-PPO） is composed of nanofibers with diameters less than 80 nm. The electrocatalytic activity of PAN-PPO for electrooxidation of oxalic acid is perfect. In situ FT-IR spectroscopy was used to investigate the electrooxidation preliminarily.
