摘要
首次将无机-有机杂化的Keggin型锗钼酸盐纳米粒子[(C2H5)4N]4GeMo12O40用做修饰剂,通过直接混合法制得了三维、体修饰的碳糊电极,并研究了该修饰电极在酸性水溶液中的电化学行为.结果表明:修饰电极充分保持了锗钼酸盐的电化学活性和碳糊电极表面可更新的特点,不仅对亚硝酸根和溴酸根的还原具有很好的电催化活性,而且还具有优良的稳定性.
Inorganic - organic hybrid Keggin - type germanomolybdate nanoparticles [（C2H5）4N]4GeMo12O40（GeMo12） was firstly used as a modifier to fabricate a three - dimensional bulk - modified carbon paste electrode （CPE） by direct mixing. The electrochemical behavior of the GeMo12 - CPE was studied in acidic aqueous solution. The results show that the GeMo12 - CPE kept the electrochemical activity of the germanomolybdate and surface- renewability of the CPE. The GeMo12 - CPE not only showed good electrocatalytic activity toward the reduction of nitrite and brornate, but also possesses excellent stability, which is owed to the insolubility and strong adsorption on the graphite powder of the hybrid germanomolybdate nanoparticles.
