摘要

These days, as development advances, pollution also rises. Organic contaminants from the chemical and agricultural sectors are discharged directly into water sources, damaging aquatic ecosystems; pesticides adversely affect the environment and create numerous challenges in our lives. Therefore, innovative and efficient solutions must be created to mitigate or eliminate the negative impact of the agricultural carbofuran pesticide component on the environment due to its contamination of aquatic bodies. Extensive research has been done looking at the possibility of using a photocatalyst to degrade organic and inorganic contaminants. g-C3N4 Because of their cheap cost, ease of manufacture, high stability, and unique physicochemical features, nano-composites have become an increasingly popular issue in the area of material science. It is a polymeric material composed of carbon, nitrogen. Carbon nitrides possess distinctive semiconducting properties and demonstrate remarkable catalytic activity across various processes; the catalytic efficacy of g-C3N4 can be enhanced through doping with transition metals like La2O3 and V2O5, attributable to the semiconducting nature of carbon nitrides. The V2O5-doped graphitic carbon nitride photocatalysts demonstrate improved visible-light photo-catalytic action, essential for the mineralization of carbofuran. The synthesized material was evaluated using XRD, TGA, FT-IR, FE-SEM, and UV-DRS. The band gap of synthesized material was also done us UV–VIS-NIR spectroscopy. Indeed, under visible light for 120 min the degradation was more than 80% using ternary nanocomposite. Markedly, the ternary nanocomposite shows a higher efficiency than the pure g-C3N4.
