High-Entropy Oxide Nanocatalysts for Water Electrolysis: Structure–Activity Relationships and Device Prospects

Green hydrogen is a key energy vector for low-carbon transition, yet water electrolysis remains constrained by sluggish reaction kinetics and the high cost of noble-metal catalysts. High-entropy oxides (HEOs), which contain multiple metal cations, exhibit characteristic high-entropy, lattice-distortion, sluggish-diffus...
