This perspective will give an overview of the studies of O 2 reactions with the hydrogenases and biomimetics with focus on our recent studies that compare sulfur and selenium containing synthetic analogues of the –H 2ase active sites. Despite the evidence of S/Se-oxygenation in the active sites of hydrogenases, there are limited reported synthetic models. Exposure to O 2 typically leads to irreversible damage. The analyses of the driving performance, distraction and attention measures were carried out within 3 x 4 mixed model ANOVA with age group (Young Drivers. In contrast, the –H 2ase active site has less possibilities for chalcogen-oxygen uptake and a greater chance for O 2-attack on iron. The affinity of oxygen for sulfur, in –H 2ase, and selenium, in –H 2ase, yielding oxygenated chalcogens results in maintenance of the core NiFe unit, and myriad observable but inactive states, which can be reductively repaired. In the hydrogenase active sites oxygen damage may be extensive (irreversible) as it is for the –H 2ase or moderate (reversible) for the –H 2ases. ![]() The -H 2ases and some of the –H 2ases, biocatalysts for reversible H 2 production from protons and electrons, are exemplars of oxygen tolerant HER catalysts in nature. At some point, all HER (Hydrogen Evolution Reaction) catalysts, important in sustainable H 2O splitting technology, will encounter O 2 and O 2-damage.
