Solvent-Assisted Synthesis of Supramolecular-Assembled Graphitic Carbon Nitride for Visible Light Induced Hydrogen Evolution - A Review
Abstrakt
Many graphitic carbon nitride (g-C3N4)-based photocatalysts have attracted a significant interest because of the unique arrangement of carbon and nitrogen atoms. Changeable morphologies with tunable bandgap of g-C3N4 materials were used in many applications including batteries, photovoltaics, photocatalysts, sensors, etc.
This review focuses on the recent progress in the solvent assisted supramolecular-assembled carbon nitride preparation for visible light induced hydrogen evolution from water. The synthesis involves tailoring the supramolecular assembly from different monomers followed by calcination.
Different types of non-covalent interactions between the monomers have been explained. In addition, the crucial role of solvent has been re-counted in terms of the alteration of the structural morphology of assemblies.
The mechanistic pathways of interaction in the formation of supramolecular assemblies have been also documented by molecular dynamics simulation. Finally, visible light triggered hydrogen evolution has been demonstrated along with discussion on challenges and future research direction.
