The electrochemical sensing property of multi-layer graphene nanobelts (GNB) towards hydrazine is studied. The developed hydrazine sensor showed a sensitivity value of 0.08 μA μM−1 cm−2 with a linear range of 10 μM to 1.36 mM. The interference data also exhibited high selectivity to hydrazine even in the presence of common interfering species like ascorbic acid, uric acid, glucose and lactic acid.
