A novel strategy to fabricate hydrogen peroxide (H 2 O 2 ) sensor was developed by electrodepositing palladiumsilver nanoparticles (NPs) on a glassy carbon electrode. The morphology of the modified electrode was characterized by Scanning electron microscopy (SEM). The result of electrochemical experiments showed that such constructed sensor had a favorable catalytic ability, high sensitivity, excellent selectivity towards reduction of hydrogen peroxide (H 2 O 2 ). The response to H 2 O 2 is linear in the range between 0.30 μM to 2.50 mM, and the detection limit is 0.1 μM (at an S/N of 3).
