Abstract Electrocatalytic water splitting is an attractive approach for large‐scale hydrogen generation, critical global carbon neutrality. However, the prevalent commercialized alkaline electrolysis generally conducted at low current densities due to sluggish kinetics and high overpotential, severely hampering high‐efficiency production. Exploration of evolution reaction (HER) electrocatalysts that can reliably operate ampere‐level under overpotentials thus a primary challenge. In contrast extensive studies using powdery electrocatalysts, self‐supported metallic catalytic cathode has become burgeoning direction toward densities, owing their integrated design with intensive interfacial binding, conductivity mechanical stability industrial tolerance/adaption. Recent years have witnessed tremendous research advances in designing electrocatalysts. Therefore, this flourishing area specially summarized. Beginning introduction theory mechanism HER, engineering strategies on electrodes are systematically summarized, including metal alloy construction, heterostructure engineering, doping manipulation, surface design. Meanwhile, particular emphasis focused relationship between structure, activity, HER. Finally, existing challenges, requirements industrial‐scale application, future aiming provide better solution electrolysis.

Abstract Alkaline water splitting has shown great potential for industrial‐scale hydrogen production. However, its broad application is constrained by evolution reaction (HER) electrocatalysts, which struggle to achieve optimal current density at low overpotential. The utilization of the spillover effect augment performance HER represents a burgeoning area research. Although previous studies mainly focused on in acidic media, latest have that also exists under alkaline conditions, and role improving cannot be ignored. This review examines mechanisms elucidating distinctive behavior these environments influence catalytic processes. At same time characterization methods are systematically summarized, technologies understanding control release process provides strong support. Finally, recent electrocatalysts enhance comprehensively sorted out summarized. not only demonstrate practical value but provide new directions future design optimization electrocatalysts.
