Catalytic activity of photocharged binary TiO2 and WO3 membrane filters: Effect of Al2O3 interlayer on direct vs. mediated electron transfers
Jiyeon, Park; Kim, Bolam; Han, Dong Suk; Lim, Jonghun; Park, Hyunwoong ( Elsevier , 2022 , Article)One of the challenges facing the practical application of photocatalysis is the termination of catalytic reactions in the absence of irradiation. This study synthesizes photo-charged TiO2/WO3 (TW) and TiO2/Al2O3/WO3 (TAW) ... -
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)) ...
