摘要

电解水制氢是一种前景广阔的能源转化方法，具有绿色、低碳、环保的特点，制备高效、低成本的电催化剂对提高电解水的效率至关重要。本研究采用水热法和电沉积法成功合成了Fe2WO6@Ni3S2-WS2/NF，其特殊的纳米花状结构和多组分之间的协同效应使其具有优异的催化性能和出色的稳定性。在 1.0 M KOH 中，Fe2WO6@Ni3S2-WS2/NF 在 10 mA cm-2 的条件下，氧进化反应（OER）的过电位为 170 mV，并在 100 h 内保持稳定，这表明其具有很高的催化活性和稳定性，适用于长时间的 OER 过程。Fe2WO6@Ni3S2-WS2/NF 活性的提高可归因于电子传输速率的提高、更多活性位点的暴露和导电性的改善。这项研究为制备高效、稳健的 OER 催化剂提供了一种可行的方法。

Synthesis and performance study of Fe2WO6@Ni3S2-WS2/NF for efficient electrolytic water to hydrogen

Hydrogen production from electrolytic water is a promising energy conversion method, which is green, low-carbon and environmentally friendly and it is essential to prepare efficient and low-cost electrocatalysts to improve the efficiency of water electrolysis. In this study, Fe₂WO₆@Ni₃S₂-WS₂/NF was successfully synthesized by hydrothermal and electrodeposition methods, and its special nanoflower-like structure and synergistic effect among multi-components resulted in excellent catalytic performance and outstanding stability. The overpotential of Fe₂WO₆@Ni₃S₂-WS₂/NF was 170 mV at 10 mA cm⁻² in 1.0 M KOH for oxygen evolution reaction (OER) and it remains stable over 100 h, demonstrating its high catalytic activity and stability, making it suitable for prolonged OER processes. The increased activity of Fe₂WO₆@Ni₃S₂-WS₂/NF can be attributed to the improved electron transport rate, the exposure of more active sites and the improved conductivity. This study provides a viable method for the preparation of efficient and robust OER catalysts.
