Résumé :
|
The preservation of the environment and the resolution of ecological problems are essential for sustainably improving the quality of life and promoting sustainable development. Photocatalysis assisted by semiconductors is garnering increasing interest due to its immense potential to address global energy and environmental challenges. This thesis explores the design and evaluation of advanced hybrid nanomaterials for the photocatalytic degradation of organic pollutants in wastewater, specifically targeting recalcitrant dyes such as methylene blue and Biebrich scarlet. The main objective is to develop innovative photocatalysts based on zinc, bismuth, and graphitic carbon nitride (g-C₃N₄), by integrating green synthesis methods to minimize the environmental impact of manufacturing processes. The results demonstrate a rGOnanocomposites,ensuringcompletedegradationof methylene blue in 140 minutes under UV irradiation. Moreover, the Bi₁₂ZnO₂₀/Bi₂O₃ composite demonstrated exceptional performance in the degradation of Biebrich scarlet, achieving a degradation rate of 100% in just 80 minutes. Moreover, doping g-C₃N₄ with phosphorus and titanium has significantly improved its photocatalytic activity under visible light, allowing forthecompletedegradation ofBiebrichscarletin100minutes.Thesestudieshighlightthepotential of hybrid materials developed for practical applications in wastewater treatment, while emphasizing the importance of eco-friendly synthesis strategies for sustainable water resource management.
