一種可在鹼性和酸性條件下高效析氫且具有納米海綿結構的自支撐高熵金屬玻璃
- Inspired by the recently promising high-entropy concept with inherent multinary nature and glassy alloy with chemical homogeneity and tunability, we present a scalable strategy to alloy five equiatomic elements, PdPtCuNiP, into a high-entropy metallic glass (HEMG) for HER in alkaline and acidic conditions.
- Surface dealloying of the HEMG creates a nanosponge-like architecture with nanopores and embedded nanocrystals that provide abundant active sites to achieve outstanding HER activity.
- The obtained overpotentials at the current density of 10 mA cm-2 are 32 and 62 mV in 1.0 M KOH and 0.5 M H2SO4 solutions, respectively, outperforming most currently available electrocatalysts.
