Fabrication of novel SnO2-Sb/carbon aerogel electrode for ultrasonic electrochemical oxidation of perfluorooctanoate with high catalytic efficiency

Boron doped diamond electrooxidation of 6:2 fluorotelomers and perfluorocarboxylic acids. Application to industrial wastewaters treatment

“…Most of the previous research on PFASs electrochemical treatment was focused on testing different anodic materials, and was conducted with model solutions of a single compound, usually PFOA. In this way, "non-active" anodes such as SnO 2 , PbO 2 and boron doped diamond (BDD) provided high mineralization ratios of some perfluorocarboxylic (PFCAs) and perfluoroalkane sulfonic acids (PFSAs) [13][14][15][17][18][19][20]. In contrast, a poor performance for PFOA degradation was obtained when using "active" anodes, such as Pt, Ti/Ru-IrO 2 , and Ti/SnO 2 -Sb/MnO 2 [14,21].…”

Występowanie perfluorowanych związków organicznych w środowisku i fizykochemiczne metody usuwania ich z roztworów wodnych

“…Uzyskana skuteczność usuwania PFOS i PFOA mieściła się w zakresie 69 -100% [63]. Istotną wadą AC jest jego regeneracja, a ze względu na dużą stabilność perfluorowanych związków alifatycznych nie mogą być one rozłożone poprzez zastosowanie konwencjonalnych metod biologicznych i utleniania [75].…”

Preparation, characterization and environmental application of the composite electrode TiO2‐NTs/SnO2—Sb with carbon aerogels

“…Wang et al used their CA electrode to catalyze the degradation of high concentration p ‐nitroaniline under visible light . Zhao et al proposed a SnO 2 —Sb/CA electrode, which they used to oxidize perfluorooctanoate . However, use of CAs in DSA electrodes has not been reported in the previous literature …”

“…33 Zhao et al proposed a SnO 2 -Sb/CA electrode, which they used to oxidize perfluorooctanoate. 34 However, use of CAs in DSA electrodes has not been reported in the previous literature. 35 In the present study, first, a method including electrodeposition and brushing was applied to fabricate SnO 2 -Sb with CAs (TSS-CAs), in order to enhance adsorption capacity and electrochemical performance.…”
