The large amount of microplastic pollution in the aquatic environment has been regarded as a major challenge facing the world.Although some traditional water treatment processes can effectively remove microplastics in the millimeter range,research is still needed to solve the problem of removing smaller microplastics.Here,we made a durable zinc metal-organic framework-based composite material ZIF-8@Aerogel by in situ growing ZIF-8 on wood aerogel fibers,which can successfully remove microplastics in simulated water and seawater.The removal efficiencies on micro/nano plastics including poly(1,1-difluoroethylene)(60-110 nm) and polystyrene(90-140 nm)reached 91.4％ and 85.8％,respectively.This work is expected to provide a new and efficient way to remove small-sized microplastic particles in the environment.
