▎ 摘　　要

NOVELTY - Floating superhydrophilic cadmium sulfide/reduced graphene oxide composite aerogel comprises cadmium sulfide nano flakes which are uniformly loaded on the reduced graphene oxide aerogel, which has a macro structure with a diameter of 20 mm and a height of 30 mm, in which the loading amount of cadmium sulfide is 62.5-89.3 wt.%. USE - The composite aerogel is used for the photocatalytic degradation of hydrophilic antibiotic contaminants. ADVANTAGE - The composite aerogel has simple preparation process, adopts cheap and easily available raw materials, and has excellent economic and social benefits. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite aerogel, which involves adopting a one-step in-situ synthesis hydrothermal method.
