吸附在银电极上的 4,4'-联吡啶单层的质子耦合氧化还原循环可催化增强碱性和中性溶液中的析氢反应。通过一个 N 端的特异性吸附促进了不稳定的 N,N-二氢联吡啶的电化学形成，并且其分解产生 H2。
The proton-coupled redox cycle of 4,4'-bipyridine monolayer adsorbed on an Ag electrode catalytically enhances hydrogen evolution reactions in basic and neutral solutions. The specific adsorption via one N-end facilitates electrochemical formation of an unstable N,N-dihydro bipyridine and its decomposition yields H2.
