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

Electrochemical treatment of endocrine-disrupting chemical from aqueous solution

“…It was known that hydroxyl radicals were generated during the reaction, a part of which were used to oxidize BPA, and another part for oxygen evolution side reaction. So with increasing the current density, the formation rate of hydroxyl radicals enhanced, which resulted in the obvious increase of degradation efficiency [42].…”

Fabrication of cerium-doped lead dioxide anode with improved electrocatalytic activity and its application for removal of Rhodamine B

“…The wide use of cerium as a catalyst in oxidation reactions [18,19] suggests that cerium oxide is a promising candidate as a dopant to improve the electrocatalytic activity and stability of PbO 2 electrodes. Meanwhile, vertically aligned titanium dioxide nanotubes (TiO 2 -NTs) prepared on Ti substrate by anodic oxidation can serve as a novel underlay for PbO 2 and greatly increase the loading capacity of PbO 2 [10]. To the best of our knowledge, few studies on the direct loading of Ce-PbO 2 onto TiO 2 -NTs have been reported.…”

“…PbO 2 , one of the most commonly used electrodes in EO, has been widely studied [4,[9][10][11]. Compared to other electrode materials, PbO 2 has many advantages, including excellent conductivity, high O 2 -overvoltage, strong oxidizing capability and low cost.…”

Anodic Materials with High Energy Efficiency for Electrochemical Oxidation of Toxic Organics in Waste Water

“…For waste water treatment, due to its relative high cost compared to the most favorable biological process, the electro oxidation process was usually used to oxidize organic wastes which are toxic and resistant to biological treatment. These organic compounds usually include phenol (Andrade et al, 2008;Tahar & Savall, 1999), aniline (Hmani et al, 2009), benzoquinone, chlorinated phenol (Cao et al, 2009;Tan et al,2011), nitrophenol (Liu et al, 2008a), naphthol (Panizza & Cerisola, 2003;Panizza & Cerisola, 2004), cyanide (Hine et al, 1986), benzene (Hamza et al, 2011), cresols (Flox et al, 2009), chloranilic acid, indoles, tannic acid, 1,2-dichloroethane, herbicides (Panizza et al, 2008), pesticides (Youssef et al, 2010), surfactants (Weiss et al, 2006) and dyes. Borras et al (2003) studied the initial stages of oxidation of aqueous solutions of pchlorophenol (p-CP) and p-nitrophenol (p-NP) on Bi-doped PbO 2 electrodes.…”

“…Bartlett et al (2002) deposited lead dioxide onto self-assembled polystyrene microspheres and then the polystyrene was dissolved out by an organic solvent to get a highly ordered lead dioxide nano-structure. Tan et al (2011) prepared nano lead dioxide by employing self-organized TiO 2 nanotube arrays as substrate.…”
