Preparation of CdS/graphene Hybrid Aerogels with Effective Photocatalytic Activity

Abstract

In this study, we report a facile and one-step method to synthesize CdS/graphene hybrid aerogels (CdS/GA). XRD, FTIR, Raman, XPS spectroscopy, and FESEM technique were applied to characterize the structure and morphology of the aerogels, and the results confirmed that the CdS/GA exhibited a 3D interconnected macroporous framework of graphene sheets with uniform dispersion of CdS nanoparticles. Due to the good absorption property and the reduction of electron-hole pair recombination in CdS, the CdS/GA composites have an excellent photocatalytic activity for MO and RhB under UV irradiation.
