Abstract
Defect engineering by heteroatom doping gives carbon materials some new characteristics such as a different electronic structure and a high electrochemical activity, making them suitable for high-performance applications. N-doping has been widely investigated because of its similar atom radius to carbon, high electronegativity as well as many different configurations. We summarize the preparation methods and properties of N-doped carbon materials, and discuss their possible use in sodium ion storage. The relationships between N content/configuration and crystallinity, electronic conductivity, wettability, chemical reactivity as well as sodium ion storage performance are discussed.
通过掺杂杂原子进行缺陷工程可赋予碳材料一些新特性，如不同的电子结构和高电化学活性，使其适用于高性能应用。由于 N 原子半径与碳相近、电负性高且具有多种不同的构型，因此 N 掺杂已被广泛研究。我们总结了掺 N 碳材料的制备方法和特性，并讨论了它们在钠离子存储中的可能用途。讨论了 N 含量/构型与结晶度、电子导电性、润湿性、化学反应性以及钠离子存储性能之间的关系。
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.
