The development of high-performance catalysts plays a crucial role in facilitating chemical production and reducing environmental contamination. Single-atom catalysts (SACs), a class of catalysts that bridge the gap between homogeneous and heterogeneous catalysis, have garnered increasing attention because of their unique activity, selectivity, and stability in many pivotal reactions. Meanwhile, the scarcity of precious metal SACs calls for the arrival of cost-effective SACs. Cobalt, as a common non-noble metal, possesses tremendous potential in the field of single-atom catalysis. Despite their potential, reviews about single-atom Co catalysts (Co-SACs) are lacking. Accordingly, this review thoroughly summarized various preparation methodologies of Co-SACs, particularly pyrolysis; its application in the specific domain of organic synthesis and environmental remediation is discussed as well. The structure-activity relationship and potential catalytic mechanism of Co-SACs are elucidated through some representative reactions. The imminent challenges and development prospects of Co-SACs are discussed in detail. The findings and insights provided herein can guide further exploration and development in this charming area of catalyst design, leading to the realization of efficient and sustainable catalytic processes.
高性能催化剂的开发在促进化学生产和减少环境污染方面起着至关重要的作用。单原子催化剂（SACs）是一类弥合均相催化和非均相催化之间差距的催化剂，由于其在许多关键反应中具有独特的活性、选择性和稳定性，因此受到越来越多的关注。同时，贵金属单原子催化剂的稀缺性促使具有成本效益的单原子催化剂的出现。钴作为一种常见的非贵金属，在单原子催化领域具有巨大的潜力。尽管它们具有潜力，但关于单原子钴催化剂（Co-SACs）的综述却很缺乏。因此，本综述全面总结了Co-SACs的各种制备方法，特别是热解；还讨论了其在有机合成和环境修复特定领域的应用。通过一些代表性反应阐明了Co-SACs的构效关系和潜在催化机理。详细讨论了Co-SACs面临的紧迫挑战和发展前景。本文提供的研究结果和见解可以指导在这个迷人的催化剂设计领域进行进一步的探索和开发，从而实现高效和可持续的催化过程。
