ZnS nanowalls, microspheres and rice-shaped nanoparticles have been successfully grown on graphene oxide (GO) sheets bythe hydrothermal method. The morphologies, structures, chemical compositions and optical properties of the as-synthesizedGO/ZnS have been characterized by X-ray power diff raction, energy dispersive spectrometer, scanning electron microscope,Raman spectra, photoluminescence spectroscopy and ultraviolet–visible absorption spectroscopy. It was found that theconcentration of CTAB and the reaction temperature were important in the formation of GO/ZnS microstructures. The photocatalyticactivity of the as-synthesized GO/ZnS was investigated through the photocatalytic degradation of textile dyeingwaste. Results showed that the catalytic activity of the GO/ZnS porous spheres to methyl orange and methylene blue is higherthan those of other samples. The degradation rates of methyl orange and methylene blue by porous spheres in 50 min were97.6 and 97.1%, respectively. This is mainly attributed to the large specifi c surface area of GO/ZnS porous spheres and highseparation effi ciency between photogenerated electron and hole pairs.
