The oxygen vacancy (Vo) is closely related to the activity of hydrogen evolution reaction (HER) in electrocatalysts. However, the role of vacancy defects and their concentration effects remain unclear. Here, we selected Bi₂O₃ as a model, which is an unfavorable electrocatalyst for HER due to its non-ideal Gibbs free energy of hydrogen adsorption (ΔGₕ), to … Read more
