摘要
以高纯钛片为基体,先通过阳极氧化法制得TiO2电极,再通过脉冲电沉积得到掺杂Cu2O的Cu2O/TiO2电极。采用X射线衍射仪(XRD)、扫描电镜(SEM)和循环伏安(CV)曲线测试,对比了TiO2电极和Cu2O/TiO2电极的组织结构和氧化还原能力,重点研究了Cu2O/TiO2电极在高锰酸盐指数测定中应用的可行性。结果表明,Cu2O/TiO2电极具有较强的氧化还原反应能力,比TiO2电极更适用于光电催化法对高锰酸盐指数的测定。
A Cu2O-doped TiO2(Cu2O/TiO2)electrode was obtained by pulse electrodeposition of Cu2O on a TiO2 electrode prepared via anodic oxidation using highly pure titanium plate as substrate.The microstructure and redox activity of TiO2 and Cu2O/TiO2 electrodes were compared by X-ray diffractometry(XRD),scanning electron microscopy(SEM),and cyclic voltammetry(CV).The feasibility of using the Cu2O/TiO2 electrode in determination of permanganate index was studied.The Cu2O/TiO2 electrode is more suitable than the TiO2 electrode for the photoelectrocatalytic determination of permanganate index due to the fact that the former has better redox activity.
