Abstract

Metal single atom catalysts (SACs) have been attracting increasing attention in recent years owing to their incredible performance in several key catalytic reactions such as the oxygen reduction reaction and CO oxidation. The construction of well dispersed stable SACs can not only make it possible to understand the catalytic reactions on the atomic scale, but is also important for developing novel industrial catalysts. Recent efforts have been focused on dispersing metal SACs on carbon substrates rather than on metals or metal oxides for improved catalytic behavior. Especially, graphene-based materials have proven to be excellent candidates for supporting SACs due to their unique structural and electronic properties. Nevertheless, the anchoring mechanism between metal SACs and carbon substrates is not well understood. Here we review the many roles of carbon materials as the support of SACs and highlight the anchoring mechanism. We also propose some suggestions to improve the experimental and theoretical research methods to expand the number of applications and realize industrial applications.

碳载金属单原子催化剂

近年来，金属单原子催化剂因其在氧还原反应和CO氧化等关键催化反应中的优异表现而受到越来越多的关注。构建分散良好的稳定sac不仅可以在原子尺度上理解催化反应，而且对开发新型工业催化剂具有重要意义。最近的研究重点是将金属SACs分散在碳基上，而不是分散在金属或金属氧化物上，以改善催化行为。特别是石墨烯基材料，由于其独特的结构和电子性能，已被证明是支持sac的优秀候选者。然而，金属SACs与碳基质之间的锚定机制尚不清楚。在此，我们回顾了碳材料作为sac支持的许多作用，并强调了锚定机制。提出了改进实验和理论研究方法，扩大应用范围，实现产业化的建议。

期刊介绍： New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
