| 摘 要： | 采用电化学手段测试了联合使用硝基铬酞菁和二氧化锰催化剂修饰电极对氧的催化还原性能,考察了修饰电极对氧还原的动力学特征,结果发现：二氧化锰的加入可以显著提高对氧的催化性能;峰电流与扫描速率成正比,催化氧还原的电极过程受表面吸附控制;联合使用硝基铬酞菁和二氧化锰后,催化氧还原的起始电位与单一使用硝基铬酞菁相比正移了51 mV。

| Abstract: | The catalytical properties of a combined use of tetra-nitro chromium phthalocyanine and manganese dioxide were tested by electrochemical method.The results showed that catalytic properties can be improved significantly by combined use of tetra-nitro chromium phthalocyanine and manganese dioxide;the peak currents were proportional to the scan rate,indicating that peak currents were surface-adsorption-controlled in this range of scan rate.the initial potential for oxygen reduction was shifted 51mV to relative. |
