In this study, zinc oxide was synthesized by the precipitation method. Graphene oxide (GO) was prepared by oxidation of graphite powder using a microwave pretreatment. This GO was used for the modification of the photocatalytic properties of ZnO. Fixation of particles was carried out using a photoassisting technique by visible light irradiation. Characterization of the material consisted in morphology, crystalline structure and optical properties and these were performed by XRD, SEM, BET and UV-Vis spectrometry, respectively. Photocatalytic evaluation of the material towards the water splitting reaction was followed by gas chromatography, using a metal halide lamp of 250W as a light source in a quartz-sealed photocatalytic reactor, obtaining a production of 1,200 μmolH2/g, showing an enhanced photocatalytic activity compared to ZnO.
