摘要:Abstract: Dendritic nanostructure silver material was synthesized on the surface of gold foil under the condition of being immersed in AgNO3 solution by electro deposition method at room temperature, with applied voltage (−0.3 V), electrodeposition time (60 s), electrolyte containing KNO3 (0.1 M) and AgNO3 (20 mm). The prepared materials were characterized by SEM, TEM, XRD, EDX methods. The dendritic nano silver crystal structure and formation mechanism were analysed according to the characterization results. Compared with bare Au electrodes without any modification, the Au electrode modified with silver nano material has an obvious reduction peak of hydrogen peroxide at −0.35 V. It is proved that the dendritic nano silver has a good catalytic effect on the reduction of hydrogen peroxide.
