“…67,68 Although avoiding the scaling relationship between the adsorption energy of OH* and OOH* can reduce the OER overpotential, a large number of studies have shown that the enhanced OER kinetics are often offset by structural instability, which is mainly due to the cationic dissolution of M under anodic acid conditions. 69,70 Worse yet, the dynamic formation of a large number of oxygen vacancies (V O ) in the OER process drives the bulk lattice oxygen to migrate to the surface to supplement the surface V O , resulting in bulk phase remodeling and insufficient persistence. Therefore, although LOM-based catalysts have higher catalytic efficiency, they are considered uncompetitive in terms of stability and feasibility in practical applications.…”
