【摘要】 本文使用钛片作为集流体制作了掺杂不同含量SnO2析氢抑制剂的炭电极,同时采用了循环伏安、线性扫描、恒流充放电、交流阻抗对其进行了电化学性能测试。实验结果表明,掺杂SnO2的炭电极对析氢具有明显的抑制作用,且比电容也得到了一定的提高;此外,掺杂SnO2的最佳含量为5%。更多还原

【Abstract】 In this paper,titanium plate was used as current collector added different percentage content of SnO2 to make carbon electrode,in which SnO2 was used as hydrogen evolution inhibition.In the meantime,these carbon electrodes were evaluated by cyclic voltammetry,linear sweep voltammetry,galvanostatic charge-discharge,and electrochemical impedance spectroscopy.The experimental results showed that carbon electrodes doped with SnO2 which was usually used as evolution inhibitor were signifi cantly inhibited and the ratio of the capacitance had also been improved to some extent; furthermore,the best adding proportion of SnO2 was 5 %.更多还原
