金属基复合纳米材料去除微/纳塑料研究进展OA

Metal nanomaterials have been extensively utilized in the removal of micro/nanoplastics(MPs/NPs)due to their unique optical properties,excellent photoelectrocatalytic and magnetic characteristics,as well as adsorption capabilities.High-performance metal-based composite nanomaterials have been constructed through doping,multi-element composites,functionalization,and multi-material composites,which are expected to provide a strong impetus for the efficient removal of MPs/NPs.This paper systematically reviews the preparation strategies of different metal-based composite nanomaterials and their applications in MPs/NPs removal:compared with single materials,the time required for catalytic degradation and adsorption is significantly shortened,and the removal efficiency is substantially improved.Through in-depth analysis of the removal mechanisms and key influencing factors,it provides a theoretical basis and technical guidance for developing more efficient,economical,and environmentally friendly metal-based composite nanomaterials.In the future,the development and application of multifunctional metal-based composite nanomaterials,characterized by stable performance,low cost,and strong environmental compatibility,particularly those integrating adsorption,separation,and photocatalytic functions,will represent a key research focus.The advancement of such materials is expected to provide new pathways for the efficient removal of micro-and nanoplastics through synergistic multi-technology strategies.
