▎ 摘　　要

In this work, a graphene oxide - gold nanostars modified electrode was prepared. The morphology of graphene oxide - gold nanostar films was characterized by scanning electron microscopy. The electrochemical performance of the graphene oxide - gold nanostars electrodes were analyzed by cyclic voltammetry (CV). Tests showed that the final electrode exhibited an obvious electrocatalytic effect for for the detection of nitrite.
