High concentration of nitrogen doped into graphene using N₂plasma with an aluminum oxide buffer layer

Influence of Dopant Loading on the Photo‐ and Electrochemical Properties of (N, O)‐Co‐doped Graphene.

“…Various methods have been reported for the synthesis of Ndoped graphene [(N)graphene], including electron-beam deposition, [12] arc discharge, [13] and nitrogen plasma [14,15] with the assistanceo fa mmonia,h ydrazine, or pyridine as the Ns ource. [16] One recently reported novel and convenient method [17] for Nd oping consists of the pyrolysis of natural chitosan under moderate temperatures (800-1000 8C) in the absence of oxygen to form (N, O)-co-doped graphene films on variouss upports.…”

Pristine‐Graphene‐Supported Nitrogen‐Doped Carbon Self‐Assembled from Glucaminium‐Based Ionic Liquids as Metal‐Free Catalyst for Oxygen Evolution

“…The uniform coating and the nanoparticles formed by aggregation were shown to be composed of Ndopedc arbon (see below). [50,51] Note that graphene itself will not be dopedw ith Na tt he low temperature adopted for the hydrothermalr eaction owing to the lack of active sites available for doping. The high-resolution C1sX Ps pectrum of G/GIL can be deconvoluted into two peaks at 284.…”

“…The Natoms doped into the graphene honeycombl attice break the structural symmetry,a nd therefore the intensity increase of the Db and compared with the G band could arise from the formation of N-doped carbon on the graphene, which is consistent with the XPS results. [50,51] Note that graphene itself will not be dopedw ith Na tt he low temperature adopted for the hydrothermalr eaction owing to the lack of active sites available for doping. [12,19] Hydrothermal reaction without addition of graphene wasi nvestigated to provide insight into the self-assembly mechanism.…”

p‐Element‐Doped Graphene: Heteroatoms for Electrochemical Enhancement

“…CVD, [14,15] microwave irradiation, [16] nitrogen plasma treatment, [17,18] and nitrogen-ion implantation under ultrahigh vacuum conditions [19] are some popular methods. The successful derivation of monolayer and few-layer nitrogen-doped graphenes has consistently been achieved for almost any type of synthesis method employed.…”
