Boron doped cryptomelane as a highly efficient electrocatalyst for the oxygen evolution reaction

Recent progress of manganese dioxide based electrocatalysts for the oxygen evolution reaction

“…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.…”
