摘要： 应用循环伏安法和旋转环盘电极法研究了H2 SO4 溶液中五价钒化合物 (NH4 VO3和V2 O5)的电化学行为 .由光滑Pt电极测得其CV图 ,两者的基本峰位和峰形都很相似 ,通常出现三个还原峰和三个氧化峰 ,但NH4 VO3多一个氧化峰 ,RRDE测定也出现了四个氧化峰 ,本文分析了这些对应峰的反应 ,并给予初步解释

Abstract: The electrochemical behaviors of vanadium(V) compounds(NH 4VO 3 and V 2O 5) in H 2SO 4 solutions were investigated by cyclic voltammetry (CV) and rotation ring disk electrode (RRDE) techniques. There were three anodic peaks and three cathodic peaks appeared on the CV plots at inert Pt electrode. But compared with the V 2O 5, the CV plot of NH 4VO 3 had one more anodic peak. There also appeared four anodic peaks at RRDE plots. We carefully analyzed these peaks and made some reasonable initial explaination.

Key words: Cyclic voltammetry, Rotation ring disk electrode, Vanadium(V) compounds, Electrochemical behaviors
