The influence of F− doping on the activity of PbO2 film electrodes in oxygen evolution reaction

Preparation and characteristics of a nano-PbO2 anode for organic wastewater treatment

“…It consists of ␤-phase PbO 2 crystalline phase and titanium. According to the literature [38], the doping of fluorine ions in PbO 2 will not effect ␤-phase PbO 2 crystallgraphic form significantly in comparison with undoped PbO 2 . The fluorine-doping PbO 2 anodes have higher onset overpotential for oxygen evolution and higher stability during that process.…”

Electrochemical Synthesis of Octahedral Nanostructured PbF2

“…Since F -ions can substitute hydroxide or oxygen sites, 18 anodization in the solution containing F -ions may lead to the breakdown of the bonds of Pb-(OH) 2 or Pb-O, resulting in the local etching of PbO.…”

Preparation and characterization of Ce and PVP co-doped PbO2 electrode for waste water treatment

“…Because of the easy deactivation of pure PbO 2 , the stability and electrocatalytic activity of the PbO 2 anodes are expected to be improved to further satisfy the requirement of practical application [10]. To solve this problem, recent researches have focused on modification of PbO 2 anodes by element doping, such as Bi [11,12], Co [13,14], Fe [15], polytetrafluoroethylene (PTFE) [16], Zr [17], clay [18], ionic liquids [19], Nb [20] and F [21,22]. In addition, rare earth oxides, as powerful oxidants, can easily catalyze organics compounds [23].…”
