As environmental pollutants pose a serious threat to socioeconomic and environmental health, the development of simple, efficient, accurate and cost-effective methods for pollution monitoring and control remains a major challenge, but it is an unavoidable issue. In the past decade, the artificial nanozymes have been widely used for environmental pollutant monitoring and control, because of their low cost, high stability, easy mass production, etc. However, the conventional nanozyme technology faces significant challenges in terms of difficulty in regulating the exposed crystal surface, complex composition, low catalytic activity, etc. In contrast, the emerging single-atom nanozymes (SANs) have attracted much attention in the field of environmental monitoring and control, due to their multiple advantages of atomically dispersed active sites, high atom utilization efficiency, tunable coordination environment, etc. To date, the insufficient efforts have been made to comprehensively characterize the applications of SANs in the monitoring and control of environmental pollutants. Building on the recent advances in the field, this review systematically summarizes the main synthesis methods of SANs and highlights their advances in the monitoring and control of environmental pollutants. Finally, we critically evaluate the limitations and challenges of SANs, and provide the insights into their future prospects for the monitoring and control of environmental pollutants.
由于环境污染物对社会经济和环境健康构成严重威胁，开发简单、高效、准确且经济高效的污染监测与控制方法仍然是一项重大挑战，但这是一个不可回避的问题。在过去十年中，人工纳米酶因其成本低、稳定性高、易于大规模生产等优点而被广泛用于环境污染物的监测与控制。然而，传统的纳米酶技术在调控暴露的晶体表面、成分复杂、催化活性低等方面面临重大挑战。相比之下，新兴的单原子纳米酶（SANs）因其原子分散的活性位点、高原子利用效率、可调谐的配位环境等多重优势，在环境监测与控制领域备受关注。迄今为止，在全面表征单原子纳米酶在环境污染物监测与控制中的应用方面所做的努力还不够。基于该领域的最新进展，本综述系统地总结了单原子纳米酶的主要合成方法，并突出了它们在环境污染物监测与控制方面的进展。最后，我们批判性地评估了单原子纳米酶的局限性和挑战，并对其在环境污染物监测与控制方面的未来前景提供了见解。
