Micro-Nanocomposites in Environmental Management

Water pollution, a worldwide issue for the human society, has raised global concerns on environmental sustainability, calling for high‐performance materials for effective treatments. Since the traditional techniques have inherent limitations in treatment speed and efficiency, nanotechnology is subsequently used as an environmental technology to remove pollutants through a rapid adsorption and degradation process. Therefore, here, various adsorbent and photodegradation composite materials leading to effective water remediation are summarized and predicted. Notably, recent advances in simultaneous adsorption and photodegradation micro–nanocomposites are outlined. Such materials can not only completely adsorb and remove contaminants, but the micro–nanocomposites can also be directly reused without further treatment. Finally, the future development of this unique system is discussed. Water pollution caused by oil spills, heavy‐metal wastewater discharge, and chemical‐reagent leakage is an urgent global environmental issue. The fabrication and modification of low‐cost commercial materials for adsorption and photodegradation of pollutants are reviewed.
