(506e) Multifunctional GO-COOH-Cus Nanocomposite with Enhanced Photocatalytic Activity Under Solar Light Irradiation

A multifunctional GO-COOH-CuS nanocomposite was synthesized from carboxylic acid functionalized graphene oxide and copper precursor in dimethyl sulfoxide (DMSO) by a facile and scalable room-temperature hydrothermal synthesis process. The resultant sample was characterized by TEM, FESEM, XRD, FTIR, TGA and XPS. Its photocatalytic activity was demonstrated in the photocatalytic degradation of pheno and RhB. It also showed high antibacterial activity toward E.coli and B. subtilis., and good recovery and reusability. The influence of CuS content, and the charge-transport mechanism were investigated.
