摘　　要：在nano-TiO2/CNT电极表面镀一层银,制备了Ag-nano-TiO2/CNT电极。用L-半胱氨酸(L-Cys)修饰Ag-nano-TiO2/CNT制备了L-Cys-Ag-nano-TiO2/CNT电极。研究了Ag-nano-TiO2/CNT和L-Cys-Ag-nano-TiO2/CNT的电化学性质,结果表明,L-Cys-Ag-nano-TiO2/CNT对苯乙酮有较强的催化还原作用。L-Cys-Ag-nano-TiO2/CNT modified electrode was prepared from Ag-nano-TiO2/CNT electrode by L-cysteine（L-Cys） modifying. Ag-nano-TiO2/CNT electrode was prepared by Ag plating on nano-TiO2/CNT surface. The electrochemical properties of Ag-nano-TiO2/CNT electrode and L-Cys- Ag-nano-TiO2/CNT electrode were investigated. The results showed that L-Cys-Ag-nano-TiO2/CNT electrode had a high electrocatalytic reduction capability to hypnone.
