Abstract

Au-ZnO heterostructures were fabricated on the 4-inch SiO2/Si substrates by the atomic layer deposi-tion (ALD) technique for their subsequent use as sensing electrodes in amperometric H2O2 sensor. The results showed that the sensors based on Au-ZnO heterostructures possess high sensitivity of 0.53 μAμM-1cm-2, excellent long-term stability, wide linear H2O2 detection range of 1.0 μM to 120 mM, low limit of detection (LOD) of 0.78 μM and excellent selectivity at the normal operation conditions.
