Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
