What is G C3N4?
g-C3N4 is a polymeric material composed of tris-triazine-based patterns with the C/N ratio=3/4 and small amount of H. Since it exhibits a stacked structure, g-C3N4 is often considered as sp2-hybridized nitrogen-substituted graphene. From: Energy Storage Materials, 2016.
What is a graphitic structure?
Graphite is composed of layers of carbon atoms that are arranged in 6-membered, hexagonal rings. These rings are attached to one another on their edges. Layers of fused rings can be modeled as an infinite series of fused benzene rings (without the hydrogen atoms).
What is graphitic carbon nitride used for?
Uses. A commercial graphitic carbon nitride is available under the brand name Nicanite. In its micron-sized graphitic form, it can be used for tribological coatings, biocompatible medical coatings, chemically inert coatings, insulators and for energy-storage solutions.
Which of the following dye is used in photocatalytic activity of ZnO?
The removal rate of azo dyes increased, with increased dosage of the photocatalyst and decreased initial concentration of the azo dye. The acidic condition is more favorable for degradation than alkaline condition. The degradation of azo dyes on ZnO was fitted by the first-order kinetics.
What are graphitic materials?
Graphitic materials consist of primarily carbon and exist in forms such as graphite, carbon nanotubes, graphene, and activated carbon. They are used in numerous applications in modern society.
What are g-C3N4 photocatalysts?
Due to their unique physicochemical, optical and electrical properties, a wide variety of g-C 3 N 4 -based photocatalysts have been designed to drive various reduction and oxidation reactions under light irradiation with suitable wavelengths.
How to exfoliate g-C3N4 nanosheets?
The g-C 3 N 4 nanosheets with a thickness of 2.5 nm and different degree of exfoliation could be easily achieved though directly adding controlled amount of H 2 O into a bulk g-C 3 N 4 suspension using the concentrated H 2 SO 4 as solvent.
What is g-C3N4?
The graphite-like carbon nitride (g-C 3 N 4 ), as a metal-free polymer n-type semiconductor, possess many promising properties, such as unique electric, optical, structural and physiochemical properties, which make g-C 3 N 4 -based materials a new class of multifunctional nanoplatforms for electronic, catalytic and energy applications [42], [43].
Can plasmonic Ag nanoparticles enhance photocatalytic activity of g-C3N4 nanosheets?
For example, Dong and coworkers deposited the monodispersed plasmonic Ag nanoparticles onto g-C 3 N 4 nanosheets to extend visible-light absorption, increase the generation of O 2− and enhance the charge separation, thus achieving the enhanced the photocatalytic activity of g-C 3 N 4 nanosheets towards oxidation of NO to final products [884].
