▎ 摘　　要

The electrochemical sensing property of multi-layer graphene nano-belts (GNB) towards hydrazine is studied. The developed hydrazine sensor showed a sensitivity value of 0.08 mu A mu M-1 cm(-2) with a linear range of 10 mu M 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.
