从基础研究和应用研究的角度出发，开发新型高效催化剂一直是多相催化研究的重要课题。在过去，碳材料被用作许多多相催化剂的载体，因为它们具有令人着迷的特性，包括高比表面积、可调节的孔隙率和功能性。最近，由于氮掺杂可以为各种感兴趣的应用定制碳的性质，新出现的掺氮碳负载金属催化剂可以说经历了很大的进步，并在过去的几十年里引起了最大的关注。与原始的碳负载金属催化剂相比，由于氮掺杂引入了多种金属载体相互作用，这些催化剂在许多多相催化反应中表现出了优异的催化性能。在这一视角下，我们重点介绍了氮掺杂碳负载金属催化剂的制备方法，以及这些催化剂在加氢、脱氢、氧化和偶联等几个工业反应中的催化应用。特别是，我们试图阐明从理论计算、广泛的表征和观察到的催化性能所获得的结构活性关联，从而为合理设计用于多相催化的先进催化剂提供指导。
Developing novel and efficient catalysts is always an important theme for heterogeneous catalysis from fundamental and applied research points of view. In the past, carbon materials were used as supports for numerous heterogeneous catalysts because of their fascinating properties including high surface areas, tunable porosity, and functionality. Recently, the newly emerging N-doped carbon-supported metal catalysts have arguably experienced great progress and brought the most attention over the last decades in view of the fact that nitrogen doping can tailor the properties of carbon for various applications of interest. Compared with pristine carbon-supported metal catalysts, these catalysts normally show superior catalytic performance in many heterogeneous catalytic reactions because of the introduced various metal support interactions from N doping. In this Perspective, we focus on the fabrication methods for N-doped carbon-supported metal catalysts and catalytic application of these fascinating catalysts in several industrially relevant reactions, including hydrogenation, dehydrogenation, oxidation, and coupling. Notably, we try to elucidate the structure activity correlations obtained from theoretical calculation, extensive characterization, and observed catalytic performances, thereby providing guidance for the rational design of advanced catalysts for heterogeneous catalysis.
