The electrocatalytic water splitting technology can generate high-purity hydrogen without emitting carbon dioxide, which is in favor of relieving environmental pollution and energy crisis achieving neutrality. Electrocatalysts effectively reduce the reaction barrier increase efficiency. Facet engineering considered as a promising strategy controlling ratio desired crystal planes on surface. Owing to anisotropy, with different orientations usually feature facet-dependent physical chemical properties, leading differences adsorption energies oxygen or intermediates, thus exhibit varied activity toward evolution (HER) (OER). In this review, brief introduction basic concepts, fundamental understanding mechanisms well key evaluating parameters for both HER OER are provided. formation facets comprehensively overviewed aiming give scientific theory guides realize dominant planes.
