Abstract

Graphene/zinc bismuthate nanorods composites have been prepared using graphene and zinc bismuthate nanorods as the raw materials. The composites are composed of graphene nanosheets with folds and wrinkles and zinc bismuthate nanorods which possesses cubic ZnBi38O58 and hexagonal graphite phases. The zinc bismuthate nanorods are dispersed on the graphene nanosheets. A pair of quasi-reversible redox cyclic voltammogram (CV) peaks exist at the graphene/zinc bismuthate nanorods composites modified glassy carbon electrode. The CV peak current linearly increases with the scan rate from 25 mV•s−1 to 200 mV•s−1. The electrochemical response is linear in the ascorbic acid concentration range of 0.0001-2 mM and the detection limit is 0.07 μM. The graphene/zinc bismuthate nanorods composites can be considered as a promising electrode materials to be utilized as the electrochemical sensor.
