In this Minireview, we discuss recent advances in understanding nanocluster and single-atom catalysts for CO and CO₂ emissions control applications. Through analyzing thermocatalytic CO oxidation and CO₂ reduction, two fundamentally and industrially important reactions, we compare representative nanocluster and single-atom catalytic systems from perspectives of intrinsic chemistry and reaction engineering. Generally, nanoclusters and single atoms display different catalytic performances (i.e., activity, selectivity, and stability) for these reactions depending on the synthesis methods, support materials, and reaction conditions. Key observations of activity and selectivity tradeoffs between nanoclusters and single-atom catalysts are highlighted. The dynamic structural responses of these catalytic species under CO oxidation or CO₂ reduction reaction conditions are also discussed. Synthetic control and detailed experimental and computational characterization of single-atom and nanocluster catalysts for CO and CO₂ conversion have led to exciting progress over the past decade. Still, more efforts are needed to understand and develop catalysts that meet the environmental, energy, and technical requirements to power a sustainable global economy.

用于热催化转化CO和CO2的纳米簇和单原子催化剂

在此Minireview中，我们讨论了在了解用于CO和CO ₂排放控制应用的纳米簇和单原子催化剂方面的最新进展。通过分析热催化CO氧化和CO ₂还原这两个从根本上和工业上重要的反应，我们从内在化学和反应工程的角度比较了代表性的纳米簇和单原子催化体系。通常，纳米团簇和单个原子表现出不同的催化性能（即，活性，选择性和稳定性）取决于合成方法，载体材料和反应条件。重点介绍了纳米团簇和单原子催化剂之间活性和选择性之间的权衡取舍。还讨论了这些催化物质在CO氧化或CO ₂还原反应条件下的动态结构响应。在过去十年中，用于CO和CO ₂转化的单原子和纳米簇催化剂的合成控制以及详细的实验和计算表征已取得了令人兴奋的进展。但是，仍需要付出更多的努力来理解和开发满足环境，能源和技术要求的催化剂，以推动可持续的全球经济发展。
