电催化产氢HER求助,LSV曲线,怎样由参比电极的数值校正为RHE电极?小弟初步接触电催化产氢HER,在由 参比电极 校正为RHE时,不知怎样校正呢?除了公式V(RHE)=V(SCE)+0.2415+0.059pH之外,看到的文献有的是采用以铂电极为工作电极,测CV曲线,在电流为0处的两个电势取平均值x,然后利用V(RHE)=V(SCE)+x来校正,如这篇文献《MoS2 Nanoparticles Grown on Graphene: An Advanced Catalyst for Hydrogen Evolution Reaction》的supporting部分,“ In all measurements, we used saturated calomel electrode (SCE) as the reference. It was calibrated with respect to reversible hydrogen electrode (RHE). The calibration was performed in the high purity H2 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. In 0.5 M H2SO4, E (RHE) = E (SCE) + 0.273 V. All the potentials reported in our manuscript are against RHE.”那这种方法和公式相比哪个更权威呢?查看更多3个回答 . 20人已关注
