▎ 摘　　要

Nitrogen-doped reduced graphene oxide (N-rGO) was obtained via high temperature heat treatment using ammonia as a nitrogen source. EDS and XPS tests revealed that the nitrogen atoms have been doped into the skeleton of graphene successfully. On this basis, hollow nanospherical cuprous oxide supported by N-rGO (HNS-Cu2O/N-rGO) was synthesized by chemical precipitation as electrode materials for detection of glucose. TEM test showed that the hollow spherical cuprous oxide has been successfully supported on the surface of N-rGO. In the case of electrochemical studies, the HNS-Cu2O/N-rGO modified glass carbon electrode presented a linear range from 4 mu M to 2.37 mM for glucose detection with a sensitivity of 2488.8 mu A.mM(-1).cm(-2), a detection limit of 2.28 mu M (S/N=3) and fast amperometric response. Furthermore, the nanocomposite displayed good selectivity for glucose detection in the presence of interferences. The entire analysis demonstrates the applicability of HNS-Cu2O/N-rGO nanocomposite as one of the futuristic sensing material for glucose detection.
