摘要

应用循环伏安法研究钛铁试剂(4,5-二羟基-1,3-苯二磺酸钠)电对(石墨基底)在水溶液中的电化学行为.实验表明,溶液pH<4时,该试剂的氧化还原反应电位较高,可逆性好.以其作正极与V(III)/V(II)负极组成液流电池,在硫酸介质中,充放电库仑效率可达90%以上,而且循环寿命较好,性能衰减小,具备作为液流电池正极活性物质的可行性.

Abstract

Effects of solution pH on the electrochemical behavior of tiron(sodium 4,5-dihydroxy-1,3-benzendisulfonic) couple(on a graphite electrode) were studied by cyclic voltammetry in aqueous solutions.It is shown that at pH<4,tiron exhibited a redox process at a relatively high potential with a good reversibility.A redox flow battery was formed employing tiron as the positive active species and V(III)/V(II) as the negative redox couple.In sulfuric acid medium,the coulombic efficiency of the tiron-V redox flow cell was more than 90% with a good cycle life.The decay in the cycle performance was minimal.Therefore,the feasibility of tiron as active materials for redox flow battery application is demonstrated.
