UV–vis spectra were recorded on a GBC Cintra 10e UV?Visible spectrometer. The electrochemical experiments were carried out with a CHI 650 °C electrochemical workstation (CH Instruments, USA) with a conventional three-electrode cell. The modified or unmodified glassy carbon electrode was used as the working electrode. The Pt wire and Ag/ AgCl (3.0 M KCl) electrode were used as the counter and reference electrodes, respectively. Cyclic voltammetric measurements were performed in a static cell while amperometric experiments were carried out in a stirred system. All solutions were purged with high-purity nitrogen for at least 20 min prior to experiments and a nitrogen environment was then kept over the solution in the cell. All experiments were performed at a temperature of 20±2 °C. Aliquots of hydrogen peroxide solution were added successively to the solution in ampero?metric experiments. Current-time data were recorded after a steady?state current had been achieved. 发自小木虫Android客户端 |

| 紫外-可见光谱用 GBC Cintra 10e紫外-可见光度计记录。电化学实验在一个带常规三电极池的CHI 650 °C电化学工作站(CH Instruments, USA) 进行。以改进或未改进玻璃碳电极为工作电极，以铂丝和Ag/AgCl (3.0 M KCl)电极分别为反电极和参比电极。环伏安测量在静态单元进行，电流则在搅拌系统测量。所有溶液在实验前经高纯度氮净化至少20分钟，随后氮环境一直维持在单元的溶液上。所有实验在20±2 °C温度进行。在测量电流的实验中持续加入数份过氧化氢溶液。在达到稳定态电流后开始记录电流-时间数据。 |
