摘要

推进可持续能源转换技术需要合理设计电催化剂，同时实现析氧反应（OER）的高效率、成本效益和操作稳定性。在本研究中，通过水热和磷化处理，在衬底碳布（NiFeP/CC）上均匀生长了磷化镍铁纳米花结构。合成的NiFeP/CC具有独特的层次结构，有效地增加了电化学活性表面积。在1 M KOH和10 mA·cm-2的电流密度下，NiFeP/CC电催化剂的过电位（η）较低，为186 mV。优异的性能是由于Ni和Fe之间的协同作用增强。此外，NiFeP/CC具有优异的耐久性，在碱性环境中保持电流密度24小时几乎没有衰减。该产品经过测试，在实际应用中验证了其稳定性和可靠性。

Nickel-Iron Phosphide Composite Material Based on Carbon Cloth as an Efficient Electrocatalyst for Oxygen Evolution Reaction.

Advancing sustainable energy conversion technologies requires the rational design of electrocatalysts that simultaneously achieve high efficiency, cost-effectiveness, and operational stability for the oxygen evolution reaction (OER). In this study, the nanoflower structure of nickel-iron phosphide was homogeneously grown on a substrate carbon cloth (NiFeP/CC) through hydrothermal and phosphating treatment. The as-synthesized NiFeP/CC possesses distinctive hierarchical architectures and efficiently augments the electrochemically active surface area. The NiFeP/CC electrocatalyst exhibited a lower overpotential (η) of 186 mV for OER at a current density of 10 mA·cm-2 in 1 M KOH. The excellent performance is attributed to the enhanced synergistic interaction between Ni and Fe. In addition, NiFeP/CC exhibits excellent durability, maintaining current density with almost no attenuation over 24 h in alkaline environments. The product has been tested, verifying its stability and reliability in practical applications.
