“…Direct electrodeposition of β-PbO 2 on Ti substrates is a simple way to prepare PbO 2 electrodes. The activity of Ti/PbO 2 can be enhanced by the incorporation of some dopants, such as metal and nonmetal ions [19,20]. The introduction of F − into the Ti/PbO 2 electrode results in a notable rise for the potential of the organics degradation.…”

Electrocatalytic oxidation is a promising process for degrading toxic and biorefractory organic pollutants in wastewater treatment. Selection of electrode materials is crucial for electrochemical oxidation process. In this study, Ti/F-PbO 2 and Ti/Sb-SnO 2 electrodes were chosen to compare their electrocatalytic characterization, which were prepared by electrodeposition and thermal decomposition method, respectively. The surface morphology and crystal structure of two electrodes were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The linear polarization curves show that Ti/Sb-SnO 2 electrodes possess higher oxygen evolution overpotential than Ti/F-PbO 2 electrodes. But the stability and corrosion resistance ability of Ti/F-PbO 2 electrode was higher than that of Ti/Sb-SnO 2 electrode. The electrocatalytic activity of Ti/F-PbO 2 and Ti/Sb-SnO 2 electrodes was examined for the electrochemical oxidation of malachite green (MG). The bulk electrolysis shows that the Ti/SbSnO 2 electrodes exhibit the higher electrocatalytic activity for the degradation of MG than Ti/F-PbO 2 electrodes, and the degradation process is good fitting for the pseudo-first order reaction. The higher electrocatalytic activity of Ti/ Sb-SnO 2 electrodes can be attributed to the higher oxygen evolution overpotential.

The influence of cerium on lead dioxide electrodeposition process on a glass carbon electrode (GCE) from lead nitrate solution was studied by cyclic voltammetry (CV), chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS). Cerium exhibit an inhibition effect on the lead dioxide electrodeposition process. Instantaneous nucleation mechanism can be found for lead dioxide electrodeposition according to Scharifker-Hills' model with three-dimensional growth, which is not influenced by the addition of cerium. The morphology and structure of Ce-doped PbO 2 electrodes were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that the adulteration of cerium can greatly decrease grain size and make the films more compact. Accelerated lifetime tests demonstrate that the adulteration of cerium can highly lengthen the service life of Ce-doped PbO 2 electrode in its practical application. Methylene blue degradation experiments reveal that the Ce-doped PbO 2 electrodes possess excellent electrocatalytic activity.

“…Whether or no, the activity and stability of obtained Ti/PbO 2 still needs to be improved for its practical application. To further improve its electrocatalytic activity and stability, many researchers have done a great deal of research on the modification of PbO 2 electrode, including doping of various ions (F − , Bi 3+ , Ce 3+ , Ru 3+ , Ag + , Co 2+ , Sn 4+ and Fe 3+ ) and incorporation of additives in PbO 2 coatings (TiO 2 , CeO 2 , polytetrafluoroethylene (PTFE), polyeth‐ ylene glycol (PEG), carbon nanotube (CNT)). Based on previous reports, it is found that the reasonable modification is beneficial for improving of electrocatalytic performance of PbO 2 electrode.…”

The Ti 4 O 7 modified Ti/PbO 2 electrodes have been prepared by electrodeposition, and investigated systemically using scanning electron microscope (SEM), Energy dispersive X-ray spectroscopy (EDS), powder X-ray diffraction (XRD), photoluminescence spectroscopy (PL), and degradation of anthraquinone dye (reactive brilliant blue KNÀR: C 22 H 16 N 2 Na 2 O 11 S 3 ). It is found that the Ti 4 O 7 modified Ti/PbO 2 electrodes possessed smaller PbO 2 crystal grains, good porous structure, enhanced oxygen evolution over-potential and higher electrical conductivity, as compared to that of Ti/PbO 2 electrode. Additionally, the Ti 4 O 7 modified Ti/PbO 2 electrode exhibited also longer accelerated lifetime, and higher photoelectrocatalytic activity for degradation of anthraquinone dye (reactive brilliant blue KNÀR) than that of Ti/PbO 2 electrode. The enhancement of the decolorization efficiency and stability for Ti 4 O 7 modified Ti/PbO 2 electrodes can be ascribed to the large electrochemical active areas, the presence of photoelectric synergism, rapid separation of photogenerated carriers, inhibition of oxygen precipitation, high current efficiency for formation of hydroxyl radicals, and the weakening of internal stress in PbO 2 coatings.
