A facile synthesis strategy of reduced graphene oxide (RGO)‐octahedral Mn 3 O 4 (oct‐Mn 3 O 4 ) nanocomposites using in situ one‐pot hydrothermal reaction was reported. The RGO‐oct‐Mn 3 O 4 nanocomposites were drop‐casted onto the surface of glassy carbon electrode (GCE) to obtain RGO‐oct‐Mn 3 O 4 /GCE. DPV results revealed that the performance of RGO‐oct‐Mn 3 O 4 /GCE towards metronidazole displayed a linear ranging from 0.1 to 9.5 μM with a detection limit of 0.037 μM. For sulfamonomethoxine, it exhibited a linear ranging from 1 to 95 μM with a detection limit of 0.27 μM. Moreover, the proposed sensor had good anti‐interference capability, high stability, satisfactory reproducibility, and was successfully applied in real samples.
