Phosphorus and Nitrogen Centers in Doped Graphene and Carbon Nanotubes Analyzed through Solid-State NMR

Graphene and carbon nanotubes (CNTs) have been investigated closely in recent years because of their apparent positive effect on the electrochemical performance of new fuel cell and battery systems as catalyst stabilizers, supports, or metal-free catalysts. This is particularly true for doped graphene and CNTs, where only a small amount of doping with nitrogen and/or phosphorus can have a remarkable effect on the material performance. A direct …
