Advanced Porous Materials for Sensing, Capture and Detoxification of Organic Pollutants toward Water Remediation

Abstract

Environmental pollution and its after-effects have become global concerns in recent years. Among all types of pollution, water pollution has been considered as a major threat in recent years; this problem will be even worse in the near future. In the 21st century, water recycling has become a crucial issue as more regions across the globe are witnessing a water crisis. Detoxification of wastewater via adsorptive removal or photocatalytic degradation for achieving purified and drinkable water has been determined as environmentally benign, energy economic and cost-effective. In this context, porous materials have gained enormous research consideration for detection of contaminants in effluents and for treatment of wastewater. A combination of high porosity, robustness and structural tunibility makes these nanosorbents stand out as materials in environmental remediation. Metal-organic frameworks, covalent organic frameworks and porous organic solids are among the versatile porous materials extensively investigated toward clean environment application. This review intends to provide a summarized compilation of recent research progress in sensing and sequestration of organic pollutants in advanced porous materials.
