▎ 摘 要
A novel assembly of SiO2 nanospheres functionalized on graphene oxide (GO) sheets was prepared by a one-step microwave-hydrothermal method. The nanocomposites were well characterized and investigated to study their Rhodamine B (RhB) adsorption capacity and their RhB reduction activity using hydrazine as a sacrificial electron donor. The SiO2-GO-RhB composites showed fluorescent properties. (C) 2014 Elsevier B.V. All rights reserved.
