The oxygen vacancy density of Fe1Co1Ox nanosheets can be tuned by varying the conditions of their hydrogenation process at low temperature and high pressure. The optimal control of oxygen vacancies in two-dimensional (2D) Fe1Co1Ox via hydrogenation can significantly improve its activity in the oxygen evolution reaction (OER).
