Electrocatalytic degradation of 4-chlorophenol on F-doped PbO2 anodes

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

“…However, PbO 2 anodes do not have satisfactory electrocatalytic ability compared with BDD anodes. To solve this problem, recent research has focused on modification of PbO 2 anodes by element doping, such as Bi [22,23], Co [24], Ce [25,26], Fe [27], PTFE [28], and F [29,30]. This paper is focused on a novel way to increase the electrocatalytic activity of PbO 2 anodes.…”

“…Nevertheless, this disadvantage has been suppressed by the development of new anode materials [2,11]. Several types of electrodes, including RuO 2 [12], IrO 2 [13], Ti/TiO 2 -RuO 2 -IrO 2 [14], Ti/SnO 2 -sb [15], PbO 2 [16], Pt-Ir [17], Pt/Ti [18], carbon nanotube [19], glassy carbon [20], Pt [21], three-dimensional electrode [22], and boron- doped diamond (BDD) [23] have been investigated, among which PbO 2 is one of the best candidates [24]. PbO 2 is a low-cost electrode material that can be quickly and easily prepared, and is relatively stable at high applied current density (CD) and a wide range of pH [25].…”

Formation and growth of PbO2 inside TiO2 nanotubes for environmental applications

“…Therefore, other practical options for the preparation of PbO 2 anodes need to be considered. Different kinds of PbO 2 have been prepared: pure metal oxide [24][25][26][27], mixed with other metallic oxides [29], or doped with different ionic species [16,[30][31][32][33][34]. Often, PbO 2 is deposited on a metallic substrate such as Ti [35,36], Au [37,38] or Pt [39,40] in order to improve its mechanical properties and to preserve its catalytic properties [28,[41][42][43].…”
