摘要

析氧反应 (OER) 在锌空气电池、燃料电池和电解水等能源储存和转换设备中都有至关重要的作用. 然而OER过程涉及四电子转移, 导致反应动力学缓慢. 尽管贵金属氧化物被认为是最先进的OER电催化剂, 但昂贵的价格以及稀缺性限制了其商业应用. 因此, 本工作结合水热和水浴法制备了NaCu₅S₃@Ni_xFe-LDH (x = 1, 2, 3, 4) 纳米片阵列复合电催化剂. 对样品的结构进行了表征, 结果显示NaCu₅S₃和Ni₂Fe-LDH充分混合, 形成紧密结合的界面, 有利于电荷的快速转移, 这将增强两相界面处的电子调控作用, 改变其局域结构特性, 促进OER电催化性能. 电化学测试结果显示, 当电流密度为20 mA·cm^–2时, NaCu₅S₃@Ni₂Fe-LDH在1.0 M KOH电解液中的氧析出过电位仅为227 mV, 电催化性能优于原始的NaCu₅S₃ (271 mV) 和Ni₂Fe-LDH (275 mV), 并且具有长达72 h的稳定性. 此外, NaCu₅S₃@Ni₂Fe-LDH复合电催化剂具有较小的电荷转移电阻, 较大的双层电容值 (10.0 mF·cm^–2) 和电化学活性表面积 (250 cm²), 有利于OER的进行. 本工作为设计廉价、高效且稳定的OER复合电催化剂提供了切实可行的实践路径.

Abstract

The oxygen evolution reaction (OER) plays a critical role in energy storage and conversion devices such as zinc-air batteries, fuel cells, and electrolysis water. However, the OER process involves a four-electron transfer, leading to slow reaction kinetics. Therefore, it is necessary to explore an efficient, inexpensive, and durable electrocatalysts to accelerate the OER process. Noble metal oxides are considered the most advanced OER electrocatalysts, but their high price and scarcity limit their commercial applications. Thus, researchers have started exploring other low-cost materials as alternatives. Nanocomposite materials have emerged as a promising alternative to expensive and scarce noble metal oxide electrocatalysts for OER. Therefore, this work synthesizes novel nanocomposite materials, NaCu₅S₃@Ni_xFe-LDH (x = 1, 2, 3, 4) nanosheet array via hydrothermal and water bath methods. The structure and morphology of each product are characterized, indicating a tightly integrated interface between NaCu₅S₃ and Ni₂Fe-LDH, which facilitates rapid charge transfer and enhancement of electron regulation at the interface. This changes the local structure characteristics and promotes the OER catalytic performance. Electrochemical characterization results show that in a 1.0 M KOH electrolyte, the overpotential of NaCu₅S₃@Ni₂Fe-LDH for OER at a current density of 20 mA/cm² is only 227 mV, significantly lower than that of the original NaCu₅S₃ (271 mV) and Ni₂Fe-LDH (275 mV), with stability duration reaching 72 h. Electrochemical results also reveal that with the increase of overpotential, NaCu₅S₃@Ni₂Fe-LDH shows a significant oxidation peak between 1.35–1.45 (V vs. RHE), which leads to the activation of Ni²⁺ to Ni³⁺ high oxidation state. The high oxidation state of Ni will promote the OER. The NaCu₅S₃@Ni₂Fe-LDH composite electrocatalyst exhibits lower charge transfer resistance, higher double layer capacitance value (10.0 mF/cm²), and electrochemical active surface area (250 cm²), which are also beneficial to promoting OER. This study highlights the potential of nanocomposite materials as cost-effective alternatives to noble metal oxide electrocatalysts for OER. The NaCu₅S₃@Ni₂Fe-LDH composite electrocatalyst exhibits excellent OER performance with a low overpotential, high stability, and favorable electrochemical properties. This research provides a valuable insight into the design and development of efficient and sustainable electrocatalysts for energy conversion and storage applications.
