Formation of carbon nitride compounds during successive implantations in copper

Photocatalytic conversion of CO2 into methanol using graphitic carbon nitride under solar, UV laser and broadband radiations

“…The deconvolution of the C1s peak in Figure (b) implies the existence of two carbon species, in which the peak centered at 283.4 eV is due to the sp 2 carbon atoms, which are bonded to nitrogen inside trigonal carbon configuration of the aromatic structures and the peak centered at 286.1 eV is due to the tetrahedral configuration of carbon by sp 3 ‐hybridization . These two peaks are derived, respectively, from two‐coordinated C2 and C1 atoms in tri‐s‐triazine rings.…”

Hybrid thin films of graphene nanowhiskers and amorphous carbon as transparent conductors

“…The pyridinic and pyrrolic forms of nitrogen were suggested to be the main contributors in the disorder induced in as-grown materials, 8 resulting in the formation of FGWs and amorphous phase. The process is similar to the formation of carbon nitride compounds during successive nitrogen implantations in copper, 9 in which two different C-N regions exist and that they are embedded in a dominant AC matrix.…”

Facile bulk production of highly blue fluorescent graphitic carbon nitride quantum dots and their application as highly selective and sensitive sensors for the detection of mercuric and iodide ions in aqueous media

“…4b shows the XPS spectrum in the carbon 1s region, which was deconvoluted to three main Gaussian peaks (C 1 , C 2 , and C 3 ). The binding energies of 285.45 eV (C 1 ) and 286.35 eV (C 2 ) are attributed to the presence of (sp 2 ) N-C]N (sp 2 ) (carbon bonded to two nitrogen atoms) and C(-N) 3 (planar trigonal carbon geometry) respectively, 28,29 whereas the peak at 290.05 eV (C 3 ) is attributed to CO x . The decomposition of 1s N XPS spectra (Fig.…”
