This review comprehensively summarizes recent advancements in the design strategies of advanced electrocatalysts for the alkaline HOR, including alloying effects, interface engineering, lattice strain, and phase engineering, focusing on their critical roles in modulating the electronic structure and coordination environments. Finally, the review discusses current challenges and offers perspectives on the future directions for improving the performance of Ir-based electrocatalysts.

We introduce a novel synergistic catalysis system composed of single rare earth atoms (such as Tb, Ho, Gd, and Er) doped into graphitic carbon nitride supported on Pt nanoparticles (GCN-RE-Pt) to balance the tradeoff between HBE and OHBE, thereby enhancing HOR kinetics. In this system, the single rare earth atoms could promote the adsorption of hydroxyl species, facilitating hydrogen oxidation and water generation, and induce a surface charge redistribution in GCN, which modulates the electronic structure of the Pt active centers and optimizes the binding energy of adsorbed hydrogen.

This review provides a comprehensive overview of recent advancements in HEMs for ORR, beginning with an introduction to diverse classes of high-entropy systems…It then delves into the underlying structure–property correlations within these systems, highlighting how entropy-driven design strategies influence their electrocatalytic behavior. Subsequently, the latest progress in applying various high-entropy systems to the ORR is critically analyzed, with a particular emphasis on elucidating the structure–activity relationships that govern catalytic performance. Finally, we outline key challenges and future directions, offering perspectives on the rational design of next-generation high-entropy materials for electrocatalytic ORR and related applications.
