  "abstract": "Uniform and well-defined NiSnPdPtRh high-entropy alloy nanorods (HEA NRs) are successfully prepared by a one-pot microwave-irradiated strategy within 180 s. The growth mechanism involves simultaneous reduction of metal precursors, linear assembly of nanoclusters, and Ostwald ripening, with Sn and Pd playing critical roles in directing the anisotropic growth. After carbon-supported thermal treatment at 200 °C, the as-prepared NiSnPdPtRh@C-200 NRs exhibit exceptional electrocatalytic performance for acidic HER, achieving an ultra-low overpotential of 8.39 mV at 10 mA cm⁻², a very low Tafel slope of 7.92 mV dec⁻¹, and a high noble metal mass activity of 2564 A g⁻¹. Even at an industrial-level current density of 2000 mA cm⁻², an overpotential of only 196.5 mV is required. When deployed in a proton exchange membrane water electrolyzer (PEMWE), NiSnPdPtRh@C-200 NRs exhibit a low cell voltage of merely 1.85 and 1.98 V at 1.0 and 1.5 A cm⁻², respectively, and display an extremely low voltage decay of just 12.19 µV h⁻¹ after operating for 2000 h at 500 mA cm⁻². DFT calculations reveal that Pt-Pt-Rh and Ni-Pt-Pd hollow sites serve as synergistic active centres, facilitating efficient HER kinetics via a Tafel mechanism. This work provides a simple, rapid synthesis strategy for HEA nanocrystals as high-efficiency HER electrocatalysts.",
