Review on Recent Progress in Nitrogen-Doped Graphene: Synthesis, Characterization, and Its Potential Applications

Nitrogen doping has been an effective way totailor the properties of graphene and render its potential usefor various applications. Three common bonding configurationsare normally obtained when doping nitrogen into thegraphene: pyridinic N, pyrrolic N, and graphitic N. This paperreviews nitrogen-doped graphene, including various synthesismethods to introduce N doping and various characterizationtechniques for the examination of various N bondingconfigurations. Potential applications of N-graphene are alsoreviewed on the basis of experimental and theoretical studies.
