Abstract

Water pollution is becoming an unavoidable problem in today's world. Tons of dangerous pollutants are discharged into clean water every day. Pollutants in water have negative effects on the natural environment and human health and are also one of the causes of death in the world. In this regard, adsorbers and photocatalysts using nanotechnology, such as the use of organic, metallic, and non-metallic semiconductor photocatalysts, have attracted a lot of attention in the past few decades. The objective of this study is to examine the impact of various nanostructures of graphitic carbon nitride (g-C₃N₄), including nanosheets, nanotubes, and nanorods, on their performance, as well as the effectiveness of certain g-C₃N₄-based composites as adsorbents and photocatalysts in adsorption and photocatalytic processes for dye removal from wastewater. Based on previous research findings, the dye removal efficiency of g-C₃N₄ nanostructures is significantly enhanced compared to their bulk counterparts due to their higher porosity and surface area, stronger electrostatic interactions, and a greater number of active sites.
