The oxygen evolution reaction (OER) occurring at the Pb-Ag anodes in a 150 g L^-1 aqueous H₂SO₄ solution was studied in the absence (silent) and presence of ultrasonication (40 kHz, 100 % acoustic amplitude). Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), linear sweep voltammetry (LSV), and zinc electrowinning tests were conducted to analyze the electrochemical behavior of the Pb-Ag anodes during zinc electrowinning. Compared with that under silent conditions, the OER was greatly enhanced under ultrasonic conditions, and the overpotential reduction was found to be 108 mV at 35 °C at a curreUltrasonics sonochemistry107183https://www.ebi.ac.uk/biostudies/studies/S-EPMC11665674biostudies-literatureBoosting effect of ultrasonication on the oxygen evolution reaction during zinc electrowinning.PMC11665674Cui NHuang YChen ZHan GLiu BSun HYang SfalseBoosting effect of ultrasonication on the oxygen evolution reaction during zinc electrowinning.In this study, the electrochemical and anodic behaviors of Pb-Ag anodes during ultrasound-assisted zinc electrowinning were meticulously examined.
