Molecular electrocatalysts for energy-related transformations offer unique opportunities to elucidate mechanistic principles that contribute to improved rates and energy efficiency. New catalysts for electrochemical alcohol oxidation in non-aqueous conditions have been developed recently, but it is difficult to make meaningful performance comparisons between them because the different conditions used for each catalyst result in unquantified differences in driving force. The present report outlines an approach to determine the equilibrium potential for the oxidation of alcohols in organic solvents or solvent mixtures. These equilibrium potentials are then used to determine the overpotentials for a series of molecular electrocatalysts. Overall, the methodology outlined herein provides a foundation for future advances in this field and enables comparison of electrocatalyst performance under aqueous and non-aqueous reaction conditions.

用分子电催化剂在非水溶剂中测定醇氧化的过电位

用于能量相关转化的分子电催化剂为阐明有助于提高速率和能源效率的机械原理提供了独特的机会。最近已经开发出用于在非水条件下进行电化学醇氧化的新催化剂,但很难在它们之间进行有意义的性能比较,因为每种催化剂使用的不同条件会导致驱动力的无法量化的差异。本报告概述了一种确定有机溶剂或溶剂混合物中醇氧化平衡电位的方法。然后使用这些平衡电位来确定一系列分子电催化剂的过电位。全面的,
