小中大【求助】如果用铂丝做工作电极的话用什么做对电极?
DOI: 10.1038/NMAT3087
11年的这篇Nature有个关于SCE换算成RHE的测试,"We used saturated calomel electrode (SCE) as the reference electrode in all measurements. It was calibrated with respect to reversible hydrogen electrode (RHE). The calibration was performedin the high purity hydrogen saturated electrolyte with a Pt wire as the working electrode. CVs were run at a scan rate of 1 mV s−1, and the average of the two potentials at which the current crossed zero was taken to be the thermodynamic potential for the hydrogen electrode reactions",想问各位专家,能否详细说明下测试的方法,用三电极系统还是两电极,如果用铂丝做工作电极的话用什么做对电极?谢谢各位电化学高手指点。
