Title : Recent progress in nanomaterials for water treatment: Adsorption, photocatalytic, and antibacterial applications
Abstract:
Traditional water purification methods are often ineffective to removal of organic pollutants, heavy metals, and bacteria from wastewater. In recent decades, nanomaterials have gained wide attention in the treatment of wastewater due to their large specific surface area, significant reactivity, affinity for specific contaminants, etc. This review critically examines the latest advancements in nanomaterial-based water treatment, focusing on their roles as membranes, adsorbents, and photocatalysts. A detailed discussion is provided on the properties and performance of various nanomaterials, including metal oxides (e.g., TiO2, ZnO, Fe2O3, MgO, and CuO), carbon-based materials, zeolites, and MOFs materials. Special emphasis is placed on their adsorption efficiency, photocatalytic activity, antibacterial properties, and synergistic interactions for enhanced water purification. Additionally, the review highlights key challenges, limitations, and future perspectives for the large-scale application of these materials in wastewater treatment applications.
