Abstract:

An original electrode of NiAg supported on graphite modified A4 paper(NiAg@C/A) was prepared through electrodeposition and galvanic displacement without binder for H2O2 electroreduction. The morphology and phase composition of the as-prepared electrode were investigated by X-ray diffractometer(XRD), scanning electron microscope(SEM) and transmission electron microscope(TEM). And cyclic voltammetry and chronoamperometry were conducted to study the electrochemical performance of the NiAg@C/A electrode. The results reveal that the reduction current density of H2O2 on the NiAg@C/A electrode reaches 600 mA/cm in a solution of 0.6 mol/L H2O2 and 1 mol/L NaOH at -0.8 V. The NiAg@C/A electrode exhibits good stability toward the H2O2 reduction and is a good alternative for H2O2 electroreduction in the future.
