Electrocatalytic arsenite oxidation using iron oxyhydroxide polymorphs (α-, β-, and γ-FeOOH) in aqueous bicarbonate solution
Byung Guk, Kim; Park, Jiyeon; Choi, Wonjung; Han, Dong Suk; Kim, Jungwon; Park, Hyunwoong... more authors ... less authors ( Elsevier , 2020 , Article)α-, β-, and γ-FeOOH polymorphs have been synthesized and used for electrocatalytic As(III) oxidation into less toxic As(V) in aqueous bicarbonate solution. As-synthesized FeOOH electrodes exhibit unique crystalline structures ... -
In Situ-Generated Reactive Oxygen Species in Precharged Titania and Tungsten Trioxide Composite Catalyst Membrane Filters: Application to As(III) Oxidation in the Absence of Irradiation
Park, Jiyeon; Lim, Jonghun; Park, Yiseul; Han, Dong Suk; Shon, Ho Kyong; Hoffmann, Michael R.; Park, Hyunwoong... more authors ... less authors ( American Chemical Society (ACS) , 2020 , Article)This study demonstrates that in situ-generated reactive oxygen species (ROSs) in prephotocharged TiO2 and WO3 (TW) composite particle-embedded inorganic membrane filters oxidize arsenite (As(III)) into arsenate (As(V)) ...
