Electrocatalysis: Heterogeneous trimetallic phosphide (Ni₂P−Fe₂P−Co₂P−Ni₅P₄) nanorods derived from an NiFe LDH@ZIF-67 precatalyst on Ni foam (NiFeCoP/NF) as self-supported electrodes for water electrolysis are reported. The enhanced OER/HER performances for NiFeCoP/NF electrode was achieved by improving the quantity and quality of active sites, facilitating the release of O₂/H₂ bubbles, enhancing conductivity and electron transfer. Moreover, the water-alkali electrolyzer assembled by NiFeCoP/NF as both anode and cathode only needed 1.564 V to deliver 30 mA cm⁻² with an excellent stability.

多相 NiFeCoP/NF 纳米棒作为高效水电解的双功能电催化剂

电催化：多相三金属磷化物 (Ni ₂ P−Fe ₂ P−Co ₂ P−Ni ₅ P ₄ ) 纳米棒源自 NiFe LDH@ZIF-67 预催化剂在泡沫镍 (NiFeCoP/NF) 上作为水电解的自支撑电极被报道。NiFeCoP/NF 电极的 OER/HER 性能增强是通过提高活性位点的数量和质量、促进 O ₂ /H ₂气泡的释放、增强电导率和电子转移来实现的。此外，由NiFeCoP/NF组装作为阳极和阴极的水碱电解槽仅需1.564 V即可提供30 mA cm ^-2且具有优异的稳定性。
