Abstract Graphene oxide (GO) sheets exfoliated from graph- ite were wrapped on the surfaces of polymer microspheres (∼2.5 μm in diameter) to form GO-skined GO/polymer hybrid microspheres. Subsequently, anatase TiO2 nanoparticles were nucleated and grown on the GO surfaces under solvothermal conditions, meanwhile GO was reduced to reduced graphene oxide (rGO). The results of X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), and Raman spectra demonstrate the formation of TiO2/rGO/polymer com- posites. Solvothermal reaction time was found to be an impor- tant factor in the crystallinity and size of anatase TiO2 nano- particles, further in the photocatalytic activities of TiO2/rGO/ polymer composites. The new composites behaved excellent photocatalytic activities, achieving 96 % degradation of rho- damine B in 30 min under visible light. Comparing with com- mercial TiO2, the improved photocatalytic activities of TiO2/ rGO/polymer are attributed to the unique electrical conductiv- ity of rGO, the nanosized anatase TiO2 particles, and the in- teractions between them.
