The reduced graphene oxide(RGO)/γ-AlOOH hybrids with different γ-AlOOH contents were successfully prepared via a facile one-pot hydrothermal method. In these hybrids, RGO acts as a conductive linker for improving electron transport, and γ-AlOOH nanoplatelets help to adsorb the target metal ions on the electrode surface, thus facilitating the electrochemical behavior of the hybrids. The sensitivity of as-prepared RGO/γ-AlOOH hybrids toward Pb(II) was tested by square wave anodic stripping voltammograms(SWASV) and the mass ratio of graphene to γ-AlOOH was optimized to improve the sensing performance of RGO/γ-AlOOH hybrids. Owing to the superior absorbability of γ-AlOOH for heavy metal ions and excellent electrical conductivity of graphene, the detection limit of the hybrids for heavy metal ions was found to be as low as 1.5×10–11 mol/L with optimized γ-AlOOH content in the hybrids. The experimental conditions, such as pH value, mass of electrode material, and deposition time were also investigated and optimized. The as-prepared RGO/γ-AlOOH hybrids demonstrate high electrochemical activity and good sensing performance, which offers an alternative platform for the electrochemical sensors.
