Abstract In this work, iron oxide nanomaterials with different shapes and structures were used as active materials for electrode. The proposed sensitive and non-enzymatic H2O2 biosensor, based on N-doped graphene/porous Fe2O3 NRs (N-rGO/Fe2O3 NRs), exhibits good stability and reproducibility under the optimal experimental conditions. Furthermore, this H2O2 biosensor was also utilized to detect H2O2 in real sample (orange juice) and high selectivity towards H2O2 was found. Therefore, the porous N-rGO/Fe2O3 NRs composite is thought of as a potential material in biosensing and bioanalysis.
