Nitrogen self-doped graphitic carbon nitride as efficient visible light photocatalyst for hydrogen evolution

Abstract

Nitrogen self-doped graphitic carbon nitride was successfully synthesized by the co-thermal condensation of the precursor with a nitrogen-rich additive.

Oxygenated monolayer carbon nitride for excellent photocatalytic hydrogen evolution and external quantum efficiency

“…For the C 1s fine XPS spectrum of bulk g-C 3 N 4 (Figure 3c), one peak at 284.8 eV is attributed to the sp 2 C-C bonds and the other at 288.1 eV is due to sp 2 hybridized C (N-C=N). 37 As for the 8 O-g-C 3 N 4 monolayer material, the intensity of peak at a binding energy of 288.7 eV was increasesed. Generally, it represents the C 1s in the form of O=C or C-O, 38 implying the partial oxidation of C element in O-g-C 3 N 4 monolayer.…”

Complementing Graphenes: 1D Interplanar Charge Transport in Polymeric Graphitic Carbon Nitrides

“…We expect this effect to be enhanced by (intrinsic) doping, leading to a higher concentration of free polarons. [ 42 ] Furthermore, also the confi nement of carriers within a 1D channel might be advantageous for catalytic applications. As has been shown above (see Figure 4 ), recombinations are suppressed, and a larger fraction of carriers may reach the particle surface.…”

Nitrogen Functionalized Few Layer Graphene Derived from Metal-Organic Compound: A Catalyst for Oxygen Reduction Reaction

“…Fig. 3 shows the FT-IR spectra of melamine, p-Bpy-Co, p-Bpy, G-TZ-Co and HT-G-TZ-Co. g-C3N4 synthesized from melamine [41] and melamine were included as reference [42] as both of them possesses the triazine ring system. FT-IR spectra of G-TZ-Co and p-Bpy looked alike.…”
