Among the vast class of porous carbon materials, -doped porous carbons have emerged as promising materials in catalysis due to their unique properties. The introduction of nitrogen into the carbonaceous matrix can lead to the creation of new sites on the carbon surface, often associated with pyridinic or pyrrolic nitrogen functionalities, which can facilitate various catalytic reactions with increased selectivity. Furthermore, the presence of N dopants exerts a significant influence on the properties of the supported metal or metal oxide nanoparticles, including the metal dispersion, interactions between the metal and support, and stability of the metal nanoparticles. These effects play a crucial role in enhancing the catalytic performance of the -doped carbon-supported catalysts. Thus, -doped carbons and metals supported on -doped carbons have been revealed to be interesting heterogeneous catalysts for relevant synthesis processes of valuable compounds. This review presents a concise overview of various methods employed to produce -doped porous carbons with distinct structures, starting from diverse precursors, and showcases their potential in various catalytic processes, particularly in fine chemical synthesis.
在众多多孔碳材料中,氮掺杂多孔碳因其独特性能已成为催化领域颇具前景的材料。将氮引入碳质基体可在碳表面形成新位点,这些位点通常与吡啶型或吡咯型氮官能团相关,能以更高的选择性促进各种催化反应。此外,氮掺杂剂的存在对负载型金属或金属氧化物纳米颗粒的性能有重大影响,包括金属分散度、金属与载体之间的相互作用以及金属纳米颗粒的稳定性。这些效应在提高氮掺杂碳负载催化剂的催化性能方面起着关键作用。因此,氮掺杂碳以及负载在氮掺杂碳上的金属已被证明是用于合成有价值化合物的相关合成过程中有趣的多相催化剂。本综述简要概述了从各种前驱体出发制备具有不同结构的氮掺杂多孔碳所采用的各种方法,并展示了它们在各种催化过程中的潜力,特别是在精细化学合成中的潜力。
