A comparative review of the adsorption and photocatalytic degradation of tetracycline in aquatic environment by g-C3N4-based materials

Abstract

In recent times, graphitic carbon nitride (g-C3N4)-based materials (Ms) have emerged as promising adsorbents and photocatalysts to remove tetracycline (TC) from water. This review article offers a comprehensive outline of recent advances in the use of g-C3N4@Ms for the adsorption process and photocatalytic degradation of TC in an aqueous solution. Specifically, we compare the performance of various g-C3N4@Ms, including pristine g-C3N4, modified g-C3N4, and hybrid materials, for TC removal. We also discuss the mechanisms underlying the adsorption and photocatalytic degradation processes, including the role of surface functionalization, pore size distribution, and the influence of various environmental factors. Overall, this review emphasizes the potential of g-C3N4@Ms as effective adsorbents and photocatalysts to remove TC from water. However, further research is needed to optimize the performance of these materials and better understand the underlying mechanisms governing their adsorption and photocatalytic degradation processes.
