Y-mediated optimization of 3DG-PbO₂ anode for electrochemical degradation of PFOS.

ABSTRACT: In our previous study, the three-dimensional graphene-modified PbO₂ (3DG-PbO₂) anode was prepared for the effective degradation of perfluorooctanesulfonat (PFOS) by the electrochemical oxidation process. However, the mineralization efficiency of PFOS at the 3DG-PbO₂ anode still needs to be further improved due to the recalcitrance of PFOS. Thus, in this study, the yttrium (Y) was doped into the 3DG-PbO₂ film to further improve the electrochemical activity of the PbO₂ anode. To optimize the doping amount of Y, three Y and 3DG codoped PbO₂ anodes were fabricated with different Y³⁺ concentrations of 5, 15, and 30 mM in the electroplating solution, which were named Y/3DG-PbO₂-5, Y/3DG-PbO₂-15 and
