由非层状催化材料产生二维（2D）几何形状可以显著地推进电催化剂设计。三维晶格（二维非层状材料）的二维形貌提供了大的结构扭曲、大量的表面悬挂键和配位不饱和的表面原子，这可以诱导高的表面化学活性，促进反应物的化学吸附和快速的界面电荷转移，从而提高电催化性能。在这篇文章中，我们回顾了结构工程和操纵电子状态的典型策略，使2D非层状材料的独特的电催化优势。概述了最近的研究进展，在发展的二维非层状材料催化代表性的电化学反应，是必不可少的能源和可持续性，包括析氢，析氧，氧还原，和CO2还原。对于每种类型的氧化还原反应，其独特的催化性能和潜在的机制进行了讨论。还讨论了重要成就和主要挑战。
Creating two-dimensional (2D) geometry from nonlayered catalytic materials may significantly advance electrocatalyst design. The 2D morphology of three-dimensional lattices (2D nonlayered materials) offer large structural distortions, massive surface dangling bonds, and coordinated-unsaturated surface atoms, which can induce high surface chemical activity and promote the chemisorption of reactants and fast interfacial charge transfer, thereby enhancing the electrocatalytic performance. In this article, we review typical strategies for structural engineering and manipulation of electronic states to enable the unique electrocatalytic advantages of 2D nonlayered materials. An overview is presented on recent research advances in the development of 2D nonlayered materials for catalyzing the representative electrochemical reactions that are essential to energy and sustainability, including hydrogen evolution, oxygen evolution, oxygen reduction, and CO2 reduction. For each type of redox reactions, their unique catalytic performance and underlying mechanism are discussed. Important achievements and key challenges are also discussed.
