▎ 摘　　要

Inspired by nature, a zeolitic-imidazolate framework-8@reduced graphene oxide (ZIF-8@rGO) aerogel was developed to remove tetracycline (TC) from water. The ZIF-8 nanoparticles grown on the rGO aerogel act like the many tentacles of a coral to hunt TC, and the rGO aerogel not only acts as a substrate but also acts like the belly of the coral, which can accommodate a large number of pollutants. Benefiting from these advantages, the ZIF-8@rGO aerogel can decontaminate TC, and showed an excellent adsorption capacity of 1776.26 mg g(-1). Based on the experimental tests and characterization analysis, we speculated that the adsorption mechanism between TC and ZIF-8@rGO aerogel was mainly related to the hydrogen -bonding interactions, pi-pi interaction and electrostatic attraction. This discovery could be transformative for the removal of different types of pollutants by means of adjusting the functional groups of the mate-rials and their composite technology.
