Abstract

Tuning electronic configurations of active components in supported metal catalysts can be achieved via strong metal–support interaction (SMSI) between loaded metal species and support, which has a profound effect on catalytic efficiency. Distinct from conventional supports, single–atom catalysts, due to their rich unsaturated coordination metal sites and versatile electronic states, are employed as supports to load active metal species, which can manipulate the SMSI and thereby regulate catalytic performance. Although single–atom supported catalysts have demonstrated remarkable advance in catalytic capabilities, this field is still in its infancy with a large room for improvement. Here, definition, classification, and state-of-the-art characterization techniques of single–atom supported catalysts are summarily demonstrated. The enhancement mechanisms influenced by site-specific strong metal-support interaction within single–atom supported catalysts including electronic interactions and synergistic catalysis are highlighted to present their potentials and advantages for catalysis community. Moreover, various single–atom supported catalysts with advanced components are summarized to discuss the relationships between components and catalytic properties. Finally, challenges and perspectives of single–atom supported catalysts for directions of future development are provided.

单原子负载催化剂及其他
负载金属与载体之间的强金属-载体相互作用(SMSI)可以调节负载金属催化剂中活性组分的电子构型,这对催化效率有深远的影响。与传统的载体不同,单原子催化剂由于其丰富的不饱和配位金属位点和多样的电子态,被用作负载活性金属的载体,从而可以操纵SMSI,从而调节催化性能。虽然单原子负载催化剂在催化能力方面已经取得了显著的进步,但这一领域仍处于起步阶段,有很大的改进空间。本文概述了单原子负载催化剂的定义、分类和最新表征技术。重点介绍了单原子负载型催化剂中受位置特异性强金属-负载相互作用影响的增强机制,包括电子相互作用和协同催化,展示了它们在催化界的潜力和优势。此外,综述了各种具有先进组分的单原子负载催化剂,讨论了组分与催化性能之间的关系。最后,对单原子负载催化剂面临的挑战和未来的发展方向进行了展望。
