Preparation, Characterization of Graphitic Carbon Nitride Photo-Catalytic Nanocomposites and Their Application in Wastewater Remediation: A Review

Energy crisis and environmental pollution are the major problems of human survival development. Photocatalytic technology can effectively use solar energy is prospective to solve above-mentioned problems. Carbon nitride a two-dimensional polymer material with graphite-like structure. It has good physical chemical stabilities, unique electronic band structures, widely used in field photocatalysis. Graphitic carbon conjugated large π bond structure, which easier be modified other compounds. thereby surface area visible light absorption range nitride-based photocatalytic composites insignificantly increased, interface electron transmission corresponding photogenerated carriers separation streams simultaneously promoted. Therefore, present study systematically introduced basic catalytic principles, preparation modification methods, characterization calculation simulation composite materials, their application wastewater treatment. We also summarized treatment aid artificial intelligence tools. This review frontier future development prospects graphite phase composites, provide theoretical reference for purification.
