A review on graphite carbon nitride (g-C3N4)-based composite for antibiotics and dye degradation and hydrogen production

Abstract

This paper reviews recent advances in the use of graphite carbon nitride (g-C₃N₄)-based composite photocatalysts for antibiotic and dye degradation and hydrogen production. It also discusses the structure, synthesis, modification, morphology, doping, preparation, and application of a particular subject and evaluates the advantages and disadvantages of different morphologies and preparation processes. The photocatalysts based on g-C₃N₄-based composites have demonstrated great potential. The g-C₃N₄ has been modified and tailored into various novel structures and morphologies to improve its efficiency in the photocatalytic degradation of pollutants. The techniques such as doping, metal deposition, heterojunction formation, and structural tuning enhance the rate of light absorption, charge transfer, and charge separation of g-C₃N₄. This leads to improved photocatalytic performance for antibiotic and dye degradation and hydrogen production.
