Improved performance of 3D hierarchical NiAl-LDHs micro-flowers via a surface anchored ZIF-8 for rapid multiple-pollutants simultaneous removal and residues monitoring

In this paper, we report a new type of 3D [email protected] micro-flowers material consisting of sandwich-like structured 2D nanopetals (highly compact ZIF-8 film anchored on both sides of petals). ZIF-8 was successfully incorporated into NiAl-LDHs ([email protected]) via seeding strategy directed growth of ZIFs on the surface of LDHs nanopetals. The coating of ZIF-8 significantly increased the adsorption ability to organic pollutants and...
