论文简介如下：
Solid-state hydrogen storage is pivotal for the transition to a clean-energy economy, yet conventional hydrides suffer from sluggish kinetics, poor reversibility, and stringent operating conditions. High-entropy alloys (HEAs)—multi-principal-element systems stabilized by configurational entropy—offer an unexplored design space that can simultaneously optimize thermodynamics, kinetics, and stability. Here we review the recent advances in HEAs as both intrinsic hydrogen hosts and catalysts for light-metal hydrides. By exploiting the four core effects (high-entropy, lattice distortion, slow diffusion, and cocktail), HEAs create dense, tunable hydrogen adsorption sites and diffusion channels, delivering >2 wt % reversible hydrogen storage capacity near ambient and excellent cycle life without activation. Besides, the high capacity and low hydrogen-equilibrium pressure render HEAs excellent hydrogen-isotope storage, spurring recent adoption as deuterium/tritium reservoirs in fusion reactors. When deployed as nanostructured catalysts, HEAs notably enhance the hydrogen adsorption/desorption efficiency and cycling stability of MgH₂ by adjusting surface electronic and geometric structures. We outline scalable synthesis (arc-melting, microalloyed spark plasma sintering, additive manufacturing), in-situ/operando characterization, and data-driven design workflows that integrate CALPHAD, density functional theory (DFT), and machine learning to accelerate discovery. Lightweight and corrosion-resistant HEAs further extend these benefits to automotive, portable, and grid-scale storage systems. This work establishes HEAs as a transformative platform for next-generation, high-performance hydrogen storage and catalysis.
