To produce clean and green hydrogen energy from electrolytic water, better electrocatalytic materials need to be developed. Herein, we reported the development of a Ti₃C₂ MXene@Ni/Co sulfide hybrid material for the use in hydrogen evolution reaction (HER) process, which is effective and stable. The shape of metal sulfide and its interactions with Ti₃C₂ MXene caused electronic coupling. This increased both the exposed metal sulfide's active edge sites and the charge-transfer speed. When compared with pure MXene and Ti₃C₂ MXene@NiS nanostructure, Ti₃C₂ MXene@Co₄S₃ exhibited outstanding electrocatalytic activity and stability in the HER process. The unique properties of the skeletal structure and the robust interface interaction between Co₄S₃ and MXene are responsible for the superior performance of Ti₃C₂ MXene@Co₄S₃ in the HER process. Our research offers a practical method to synthesize specialized nanostructures for electrocatalysis, electronics, and other applications.

MXene 与 Ni/Co 硫化物复合材料可增强析氢反应

为了利用电解水生产清洁、绿色的氢能，需要开发更好的电催化材料。在此，我们报道了一种用于析氢反应（HER）过程的Ti ₃ C ₂ MXene@Ni/Co硫化物杂化材料的开发，该材料有效且稳定。金属硫化物的形状及其与Ti ₃ C ₂ MXene的相互作用引起了电子耦合。这增加了暴露的金属硫化物的活性边缘位点和电荷转移速度。与纯MXene和Ti ₃ C ₂ MXene@NiS纳米结构相比，Ti ₃ C ₂ MXene@Co ₄ S ₃在HER过程中表现出出色的电催化活性和稳定性。骨架结构的独特性质以及Co ₄ S ₃和MXene之间强大的界面相互作用使得Ti ₃ C ₂ MXene@Co ₄ S ₃在HER过程中具有优异的性能。我们的研究提供了一种合成用于电催化、电子学和其他应用的专用纳米结构的实用方法。
