摘要
杂原子掺杂作为一种强大的缺陷工程策略,可赋予炭材料独特的电子结构和高化学活性,对其结构调控和高性能应用潜力开发具有重要意义.氮原子具有与碳原子相似的原子半径、较高的电负性以及多种构型,因此氮掺杂炭材料得到了广泛的研究.本文主要综述了氮掺杂炭材料的制备方法和性质,并以其作为钠离子电池和钠离子电容器负极为例讨论了其应用潜力.重点详细介绍了原位和后处理的制备策略;讨论了氮含量和构型与结晶度、电导率、润湿性、化学反应活性以及储钠性能的关系.同时本文也介绍了本课题组的相关研究成果.这篇综述有望为氮掺杂炭材料的可控制备和结构设计提供有力的指导.
Abstract
Defect engineering by heteroatom doping gives carbon materials some new characteristics such as a different electron-ic 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 sum-marize 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 so-dium ion storage performance are discussed.
