Review on fabrication of graphitic carbon nitride based efficient nanocomposites for photodegradation of aqueous phase organic pollutants

Graphitic carbon nitride (g-C3N4) as a fascinating visible light active semiconductor photocatalyst has medium band gap, non-toxic nature, stable chemical structure and high thermal stability. Recently, intensive researches are focused on photocatalytic activity of g-C3N4 for wastewater treatment. This review demonstrates latest progress in fabrication of graphitic carbon nitride C3N4 incorporated nanocomposite to explore photocatalytic ability for water purification. The g-C3N4-based nano composites were categorized as g-C3N4 metal-free nanocomposite, noble metals/g-C3N4 heterojunction, non-metal doped g-C3N4, transition and post transition metal based g-C3N4 nanocomposite. Apart from fabrication methods, we emphasized on elaborating the mechanism of activity enhancement during photocatalytic process. (C) 2018 The Korean Society of Industrial and Engineering Chemistry.
