Photocatalytic degradation of rhodamine B by using a nanocomposite of cuprous oxide, three-dimensional reduced graphene oxide, and nanochitosan prepared via one-pot synthesis

A novel nanocomposite of cuprous oxide nanospheres, three-dimensional reduced graphene oxide, and nano-chitosan with diverse functionalities were prepared by a feasible one-step in situ reduction synthesis. The developed nanocomposites possess high porosity and good electrochemical performance. It exhibits higher adsorption capacity and photocatalytic performance toward rhodamine B (RhB) dye than the pristine Cu2O nanospheres and Cu2O@3D-rGO under simulated sunlight illumination.
