摘要
为了提高二氧化铅(PbO_2)电极的稳定性,以离子液体1-乙基-3-甲基-咪唑四氟硼酸盐([Emim]BF4)为添加剂,采用双脉冲电流阳极电沉积制备聚苯胺(PANI)掺杂钛基PbO_2的Ti/PbO_2-PANI复合电极,对其形貌、稳定性及电化学性能进行了考察,并与直流电沉积制得的PbO_2电极进行对比,研究结果表明,制得的Ti/PbO_2-PANI表面致密平整,电极的析氧电位达到1.70V,电极寿命为普通PbO_2电极的9倍。
In order to improve the stability of PbO2 electrode,using ionic liquid 1-ethyl-3-methyl imidazole tetrafluoroborate（[Emim]BF4）as additive,polyaniline（PANI）doped titanium based PbO2 electrode was prepared used double pulse current anodic electrodeposition.Its morphology,stability and electrochemical performance were investigated and compared with PbO2 electrode obtained by DC electrodeposition.The results showed that the surface of prepared Ti/PbO2-PANI was compact and smooth,and the oxygen evolution potential of electrode reached 1.70 V,the test life was 9 times as high as that of the ordinary PbO2 electrode.
