摘要: 采用阳极氧化和恒电位沉积法制备Pb纳米粒子修饰的多孔Ti基TiO2(Pb/nanoTiO2)膜电极.通过对不同的电沉积电位和时间对比,找出了最佳电沉积条件.SEM分析显示该膜为均匀多孔结构,Pb纳米粒子均匀地分散在TiO2膜的表面.循环伏安和计时电流法研究了L-胱氨酸在Pb/nanoTiO2膜电极上的电催化还原活性,结果表明该电极对L-胱氨酸的还原具有高催化活性和稳定性.

Abstract: The nanoporous Ti-based TiO2 films electrodes modified with Pb particles(Pb/nanoTiO2) were prepared by using anodization and potentiostatic electro-deposition.The optimum deposition conditions were determined by comparing with various deposition potentials and time.The SEM analyses indicated that the TiO2 films were homogeneous nanoporous structure,and the Pb particles well dispersed on the TiO2 films.The L-cystine electrocatalytic activity reduction on the Pb/nanoTiO2 film electrodes was investigated by cyclic voltammetry and Chronoamperometric curves.The results showed that this type of the electrode posseses high acticity and stability.

Key words: L-cystine, electrocatalytic reduction, Pb/nanoTiO2 film electrode, L-cysteine, electrodeposition
