摘要:
采用三电极体系法,通过分析K2FeO4电极的间歇放电及电极在10 mol.L-1KOH溶液中的循环伏安行为,了解K2FeO4电极的放电机制.比较K2FeO4电极放电前后的X射线衍射结果,表明K2FeO4的放电机制为固-固放电,K2FeO4的放电过程分两步进行,即Fe(Ⅵ)→Fe(Ⅴ)→Fe(Ⅲ).其放电产物形式比较复杂,最终可能转化为FeOOH,且在放电过程中,OH-,H2O等作为反应物或产物可能参与了放电过程.
Abstract:
In order to understand the discharge mechanism of K2FeO4 electrode,the intermittent discharge and cycle voltammetry(CV) behavior of K2FeO4 electrode using 10 mol·L(-1) KOH solution as electrolyte in a three-electrode system was investigated in this paper.By comparing the XRD results before and after discharge of K2FeO4 electrode,it is clear that the discharge process is a solid-solid course and may contain two steps,that is,Fe(Ⅵ)→Fe(Ⅴ)→Fe(Ⅲ).The discharge product of K2FeO4 are very complex and maybe translate into FeOOH ultimately.OH-,H2O and so on may participate in the discharge process as reactants or productions.
