Nanotechnology has driven scientific advances in catalytic materials and processes over the past few decades. Unique physicochemical and electronic properties that emerge when materials are engineered from the bulk to the nanoscale have been exploited for a wide range of applications, including environmental remediation such as catalytic pollutant destruction. Recent advances in the catalytic synthesis of fuels and value-added chemicals explore the properties of materials, noble and transition metal catalysts in particular, when they are engineered to be below nanoscale and at the single-atom limit. In addition to the maximized efficiency of atomic utilization due to size reduction, significantly reduced costs and the potential to achieve highly selective catalysis are particularly appealing to the environmental application of single-atom catalysts, overcoming certain limitations that the field has been unable to address with nanotechnology. This critical review, built upon a comprehensive discussion of fundamental properties, synthesis methods, and application examples, evaluates in depth the opportunities and challenges of single-atom catalysts as new frontier materials for environmental remediation applications beyond nanomaterials.

纳米级以下的环境材料：单原子催化剂
在过去的几十年中，纳米技术推动了催化材料和工艺的科学进步。当材料从大批量设计到纳米级时，出现了独特的物理化学和电子性质，已被广泛应用，包括环境修复，如催化污染物的破坏。燃料和高附加值化学物质催化合成的最新进展探索了材料（特别是贵金属和过渡金属催化剂）的性能，特别是当它们被设计为低于纳米级且处于单原子极限时。除了由于尺寸减小带来的最大的原子利用效率外，显着降低的成本以及实现高度选择性催化的潜力特别吸引了单原子催化剂的环境应用，克服了该领域无法用纳米技术解决的某些限制。这项至关重要的综述建立在对基本性能，合成方法和应用实例的全面讨论的基础上，深入评估了单原子催化剂作为环境修复领域的新型前沿材料（纳米材料以外）的机遇和挑战。
