Dual-phase B-doped FeCoNiCuPd high-entropy alloy (DP-B-HEA) nanoparticles were synthesized a strategy involving thermodynamically driven solid-phase diffusion. The DP-B-HEA/CNFs showed an outstanding electrochemical N reduction reaction (NRR) performance with an ammonia yield of 24.8 μmol h cm and NH faradaic efficiency (FE) of 39.2%. The optimized electronic structures of the HEA resulting from B doping led to the enhanced NRR activity and selectivity.
通过一种涉及热力学驱动的固相扩散的策略合成了双相硼掺杂铁钴镍铜钯高熵合金（DP-B-HEA）纳米颗粒。DP-B-HEA/碳纳米纤维表现出优异的电化学氮还原反应（NRR）性能，氨产率为24.8 μmol h cm，NH法拉第效率（FE）为39.2%。硼掺杂导致的高熵合金优化电子结构提高了NRR活性和选择性。
