Nitrogen doping effects on the structure of graphene

Nitrogen Doped Graphene as Potential Material for Hydrogen Storage

“…The prepared material shows two broad peaks around 25.1˚ and 43.5˚ for nitrogen However the (100) reflection corresponds to the honeycomb structure which is formed by sp 2 hybridized carbons [57]. Generally, the heteroatom (N) doping in graphene induces defect sites and destruction in the carbon lattice, these results in low crystallinity.…”

Metal–Organic‐Framework‐Derived Mesoporous Carbon Nanospheres Containing Porphyrin‐Like Metal Centers for Conformal Phototherapy

“…[ 21 ] The I D / I G ratio of ≈0.9 was quite high for a heteroatom doped carbon material, as heteroatoms generally create defects in the sp 2 carbon lattice. [ 22 ] The heteroatom doping was confi rmed by element mapping and X-ray photoelectron spectroscopy (XPS). Element mapping of PMCS (Figure 1 c-g) indicated a homogeneous dispersion of C, N, O, and Zn in the structure.…”

Chemically modified graphene and nitrogen-doped graphene: Electrochemical characterisation and sensing applications

“…Elemental, structural and surface morphological characterisation of the graphene and N-doped graphene has been carried out previously [23], one of the main conclusions being that more defects are present on nitrogen-doped graphene. …”

“…Graphene and N-doped graphene, prepared by thermal reduction of graphite oxide, were characterized in [23]. Graphite, chitosan (low molecular weight), 2,3-dihydrothieno[3,4-b]-1,4-dioxin (EDOT), glutaraldehyde, neutral red (NR) 65% dye content, nicotinamide dinucleotide, monobasic and dibasic potassium phosphate, sodium chloride and sodium poly(styrene sulfonate) (NaPSS) were from Sigma-Aldrich, Germany.…”
