【摘要】 作为形成细颗粒和臭氧的主要前体物，挥发性有机物（VOCs）对大气环境的影响尤为突出，贵金属负载型催化剂应用于VOCs的催化氧化能耗较低而被广泛应用，传统纳米催化剂存在原子利用率低、产物选择性差、成本高的问题，但单原子催化剂在此过程中展现出巨大的潜力。该文阐述了近10年贵金属负载型单原子催化剂的合成策略、结构特点，重点关注制备方法的不同带来了贵金属与载体间的结合方式的差别以及造成它们在VOCs的催化氧化活性的明显差异，同时从理论计算的角度剖析催化性能与金属/载体间相互作用关系，并分析其催化机理，针对贵金属单原子催化剂在高效去除VOCs中存在的问题进行总结并提出未来的发展方向。更多还原

【Abstract】 As the main precursors of fine particles and ozone, volatile organic compounds(VOCs) are the crucial factor on atmospheric environment. Due to the low energy consumption, noble metal-loaded catalysts have been widely used in catalytic oxidation of VOCs, traditional nano-catalysts suffer from low atom utilization, poor product selectivity, and high cost, but single-atom catalysts give a great potential in this process. This paper describes the synthesis strategies and structural characteristics of metal-loaded single-atom catalysts in the last decades. The interaction of metal/support and its resulted activities on catalytic oxidation of VOCs is stressed. Meanwhile, the interaction of metal/support is further analyzed based on the model construction and theoretical calculation. Finally, the mechanisms of VOCs combustion on noble metal single-atom catalysts are concluded, and future development direction is proposed.更多还原
