Enhanced photoelectrocatalytic degradation of bisphenol a by BiVO4 photoanode coupling with peroxymonosulfate

Peroxymonosulfate enhanced photoelectrocatalytic degradation of 17α-ethinyl estradiol

“…Lowering the PMS concentration reduces the number of sulfate radicals, resulting in poor removal of EE2. Such trends for the effect of PMS concentration were observed in other studies [25,26]. Therefore, adding PMS positively affects the PEC process by generating a higher number of radicals for organic removal.…”

Solar Energy Conversion and Storage Using a Photocatalytic Fuel Cell Combined with a Supercapacitor

“…More specifically, a CdS-sensitized TiO 2 was used as the photoanode (CdS/TiO 2 /FTO). It should be noted that a plethora of n-type semiconductor photocatalysts have been studied and published, but only a few among them have survived as a worthy choice, based on their efficiency and their stability, i.e., TiO 2 , ZnO, WO 3 , BiVO 4 , and Fe 2 O 3 [10][11][12][13]. Among these five, practically, only titania offers a PFC which can function without added electric bias.…”

Perspective on Photoelectrocatalytic Removal of Refractory Organic Pollutants in Water Systems

“…For example, enhanced removal of MO was achieved via PEC with added sulfite, in which sulfite radicals were proven to be the main reactive species . In another study, a BiVO 4 photoanode combined with PMS showed enhanced PEC removal of BPA, in which PMS acted as the electron acceptor to improve the photogenerated e – /h + separation at the BiVO 4 surface . In addition, a copper oxide (CuO)-modified titanium dioxide nanotube array (TNA)-activated PS system has also been used for the enhanced removal of trichloroethylene; this method involved the activation of PS via hydroxyl radicals, photolysis, and H + to generate sulfate radicals …”
