摘要

高效的析氢反应是清洁氢能源生产的关键。二维(2D)材料作为一种很有前途的非贵金属HER催化剂,经常受到活性位点不足和电子传递效率低等限制。本文主要关注二维材料系统中的氢溢出和反向氢溢出现象,系统地研究了这些现象如何提高HER性能的最新研究进展。讨论了氢溢出和反向氢溢出优化氢吸附/解吸动力学的基本原理和催化机理。界面工程策略,包括异质界面的构建、功函数差的调整和金属-载体相互作用的加强,是促进(逆转)氢溢出效应的有效途径,从而提高催化活性和稳定性。最后,我们概述了关键的验证方法,包括电化学测量,原位光谱和密度泛函理论(DFT)计算。本文旨在为设计和开发高效、稳定、具有溢出效应的二维HER电催化剂提供理论基础和方向指导,促进绿色氢经济的发展。

Recent advances in hydrogen spillover and reverse hydrogen spillover for the two-dimensional materials
The efficient hydrogen evolution reaction (HER) is crucial for clean hydrogen energy production. Two-dimensional (2D) materials, as promising non-noble metal HER catalysts, often suffer from limitations such as insufficient active sites and low electron transport efficiency. This review focuses on the phenomena of hydrogen spillover and reverse hydrogen spillover within 2D material systems, systematically examining recent research progress on how these phenomena enhance HER performance. We discuss the fundamental principles and catalytic mechanisms by which hydrogen spillover and reverse hydrogen spillover optimize hydrogen adsorption/desorption kinetics. Interface engineering strategies, including the construction of heterointerfaces, tuning of work function difference, and strengthening of metal-support interactions are summarized as effective approaches to promote (reverse) hydrogen spillover effects, thereby enhancing catalytic activity and stability. Finally, we outline key verification methods, including electrochemical measurements, in situ spectroscopies, and density functional theory (DFT) calculations. This review aims to provide a theoretical foundation and directional guidance for the design and development of efficient and stable 2D HER electrocatalysts leveraging spillover effects, contributing to the advancement of the green hydrogen economy.
