电催化反应中的质子耦合电子转移过程

Proton Coupled Electron Transfer in Electrocatalytic Reactions

质子耦合电子转移机理尽管已被广泛研究,但到目前为止,其在电催化机理中的应用仍含糊不清。这篇综述总结了电催化析氢,电催化析氧及醇的电化学氧化的典型机理,并强调了质子耦合电子转移过程在整个电催化循环中的地位。在电催化体系的设计中,应特别重视质子耦合电子转移途径。

Mechanisms of proton coupled electron transfer have been extensively investigated, but yet to date, their applications to electrocatalytic mechanisms are still ambiguous, This mini ＇ review summarized typical mechanisms of electrocatalytic hydrogen evolution, electrocatalytic oxygen evolution and alcohol electro - oxidation, and emphasized the role of proton coupled electron transfer process in the electrocatalytic cycle. In the design of an elec- trocatalytic system, the proton coupled electron transfer pathway should be paid special attention.
