A faciEe route was proposed to synthesize mueberry-lke goed nanospheres (MGNS) uniformey deposited on graphene nanosheets (GNs). Aniine was used as the reducing agent of both tetrachbroaurate and graphene oxide (GO). GO was partiay reduced to GNs and acted as a support of the MGNS. The influence of the reaction time, reaction temperature and anilne concentration on the morphology of the MGNS were investigated. The resulting MGNS GNs composites were characterized by transmission e[ectron microscopy, scanning e[ectron microscopy, X-ray diffraction spectroscopy, u[travio[et-visibEe spectroscopy, Fourier transform infrared spectroscopy and eEectrochemicaE techniques. The formation mechanism of the MGNS GNs was proposed based on the contrast experiments. The results illustrated that GO Ways a key ro[e in the uniform distribution of the MGNS and poEyandine is responsible for the formation of the MGNS. Compared with GO, the MGNS GNs showed an enhanced photoe[ectrochemical property, which has potential application in the fields of sensors and energy.
