Advanced porous nanomaterials as superior adsorbents for environmental pollutants removal from aqueous solutions

Abstract Advanced porous nanomaterials such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and porous aromatic frameworks (PAFs) with high specific surface areas, abundant functional groups, accessible pore structures, tunable pore sizes, and easy modification are attractive as adsorbents for the capture of toxic heavy metal ions, organic pollutants, and radionuclides from aqueous solutions. This review first comprehensively introduces the attractive properties of MOFs, COFs, and PAFs to highlight their advantages as adsorbents. Subsequently, the recent progress of MOFs, COFs, and PAFs as superior adsorbents for the efficient removal of environmental pollutants is summarized. Furthermore, the influences of environmental conditions and information about the interaction mechanisms between pollutants and advanced porous nanomaterials are discussed. Finally, the applications and promising prospects of advanced porous nanomaterials in environmental pollution management are summarized. This review is beneficial to designing and fabricating advanced porous materials, which also provides some meaningful guidance for studying the adsorption mechanisms between porous materials and environmental pollutants.

期刊介绍： Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics. Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges. The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
