[Fe-Fe]-氢化酶及其合成模型在有氧条件下的不稳定性是它们作为实用的H-2产生电极的发展中固有的挑战。研究了一系列合成的[Fe-Fe]氢化酶模型配合物的电化学氧还原反应，发现桥头氮在减少部分还原氧物种（PROS）的量方面起主导作用，而PROS的量对这些配合物的稳定性是不利的.
The instability of [Fe-Fe]-hydrogenase and its synthetic models under aerobic conditions is an inherent challenge in their development as practical H-2 producing electrodes. The electrochemical oxygen reduction reaction of a series of synthetic model complexes of the [Fe-Fe] hydrogenase is investigated, and a dominant role of the bridgehead nitrogen in reducing the amount of partially reduced oxygen species (PROS), which is detrimental to the stability of these complexes, is discovered.
