Freestanding 3D MoS2 nanosheets/graphene aerogel heterostructure as a recyclable photocatalyst for efficiently degrading antibiotic residues

Abstract To develop the high-efficient visible-light photocatalyst with good recyclability is curial for its application in environment remediation. Herein, three-dimensional (3D) MoS 2 nanosheet/graphene aerogel (MoS 2 NS/GA) has been prepared by using 3D GA as the framework from the hydrothermal method. The prepared 3D MoS 2 NS/GA is characterized and shows, even a small amount, high efficiency for photodegrading the concentrated TC-HCl. Moreover, the lost activity could be recovered by the compensation with S 2− ions.
