Abstract

Single-atom catalysts have risen significant attention in the realm of green electrocatalytic energy conversion to address energy and environmental sustainability challenges. Transition metal dichalcogenide (TMD)-based single-atom catalysts are considered highly effective in electrocatalysis due to the TMDs' notable specific surface area, tunable elemental species and efficient utilization of single atoms. In order to enhance electrocatalytic performance, it is imperative to elaborately engineer the local environment surrounding the active sites of single atoms within TMDs. In this review, we initially explore the effects of synthesis methods on single-atom active sites and the influence of loading of single atoms on catalytic performance for TMDs. The modulation strategies of the local environment surrounding single-atom sites in TMDs are elaborated, including substitution engineering, surface adsorption, vacancies, spatial confinement and dual-atom site strategies. For each modulation strategy, the effects of diverse local environments on various electrocatalytic applications are presented, such as the oxygen evolution reaction, oxygen reduction reaction, nitrogen reduction reaction, CO₂ reduction reaction and CO oxidation. Ultimately, this study presents a comprehensive overview of the challenges encountered and the potential directions for the advancement of single-atom catalysts based on TMDs in the realm of electrocatalysis.

基于过渡金属二钴化物的单原子催化剂的局部环境调控

单原子催化剂在绿色电催化能源转换领域备受关注，以应对能源和环境可持续性挑战。基于过渡金属二掺杂物（TMD）的单原子催化剂被认为在电催化中非常有效，这是因为 TMD 具有显著的比表面积、可调元素种类和对单原子的有效利用。为了提高电催化性能，必须精心设计 TMDs 中单个原子活性位点周围的局部环境。在本综述中，我们首先探讨了合成方法对单个原子活性位点的影响，以及单个原子的负载对 TMD 催化性能的影响。我们详细阐述了 TMD 中单原子位点周围局部环境的调控策略，包括替代工程、表面吸附、空位、空间限制和双原子位点策略。针对每种调制策略，介绍了不同局部环境对各种电催化应用的影响，如氧进化反应、氧还原反应、氮还原反应、二氧化碳还原反应和一氧化碳氧化反应。最后，本研究全面概述了基于 TMD 的单原子催化剂在电催化领域遇到的挑战和潜在的发展方向。
