Graphitic carbon nitride

Open access peer-reviewed chapter. Edited by Nasser S. Graphitic carbon nitride g-C3N4is a synthetic polymer made up of carbon, nitrogen, and some impurity hydrogen that is linked together using tris-triazine-based patterns. Because of the inclusion of N and H atoms, graphitic carbon nitride, it has electron-rich characteristics, basic surface functions, and H-bonding motifs, compared to the bulk of carbon materials.

Graphitic carbon nitride g-C 3 N 4 is a metal-free conjugated polymer constructed from two-dimensional sheets with a bandgap energy of 2. In the present study, the basic concepts and principles of photocatalytic water splitting have been discussed, and a guide for the selection of appropriate photocatalysts, focusing on the g-C 3 N 4 nanomaterials, has been proposed. Our approach is mainly concentrated on evaluating two factors, namely the solar-to-hydrogen STH conversion and apparent quantum yield AQY for different photocatalysts, to provide an in-depth analysis and a framework for solar H 2 production for future research directions. We compared hydrogen production from an economic viewpoint and performance of g-C 3 N 4 nanomaterials through photochemical PC and photoelectrochemical PEC methods. Various approaches for efficient solar H 2 generation over a modified g-C 3 N 4 surface with the possibility for commercialization have been introduced. The promising approaches for the effective utilization of g-C 3 N 4 are categorized into three proposed methods: electronic structure tuning, hybrid and nanocomposite fabrication, and finally geometric structure manipulation. Finally, we compared the recent findings and key achievements for g-C 3 N 4 -based photocatalysts modified based on the abovementioned three approaches to propose two possible scenarios for their use in the future development of efficient solar H 2 generation.
