In an effort to standardize the determination of overpotential values for H(2)-evolving catalysts in non-aqueous solvents and allow a reliable comparison of catalysts prepared and assayed by different groups, we propose to adopt the half-wave potential as reference potential. We provide a simple method for measuring it from usual stationary cyclic voltammograms, and we derive the formulas to which the measured potential should be compared, taking into account the effect of homoconjugation. We also revisit tabulated values of the standard reduction potential of protons in nonaqueous solvents, E(H+/H(2))°.
为了标准化非水溶剂中析氢催化剂过电势值的测定，并允许不同研究小组制备和测试的催化剂之间进行可靠比较，我们建议采用半波电势作为参考电势。我们提供了一种从常见的稳态循环伏安图中测量半波电势的简单方法，并推导了考虑同共轭效应时应与测量电势进行比较的公式。我们还重新考察了非水溶剂中质子标准还原电势 E(H+/H(2))°的表格值。
