Abstract

Developing highly active anode materials and sustainable development for zinc electrowinning to reduce energy consumption remains a challenge. In this study, PbO2 electrodes were modified using porous organic polymer (POP) with vacancies for improve their catalytic activity of the oxygen evolution reaction (OER) in zinc electrowinning. The effects of POP modification on the surface morphology and phase structure of the PbO2 electrode were investigated, revealing that POP modification altered the electronic structure of the PbO2 electrode. Theoretical calculations indicated that the POP achieved the most optimal electronic structure around Pb and O atoms. This resulted in a downshifted d-band centre, which reduced the free energy of the rate-determining step (∗O + H2O → ∗OOH + H+) of the OER while enhancing intrinsic activity. The prepared PbO2-POP electrodes exhibited excellent acidic OER performance at 50 mA cm−2 in 1.53 M H2SO4. Moreover, simulated Zn electrowinning experiments revealed that the PbO2-POP electrodes increased current efficiency of 3.56 % and reduced energy consumption of 137.16 kW h t−1 compared with traditional Pb-Ag alloys. The results contribute to the development of anodic electrocatalysts for nonferrous-metal electrowinning and sustainable development of zinc electrowinning.
