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) ... -
Porous dendritic BiSn electrocatalysts for hydrogenation of 5-hydroxymethylfurfural
Piao, Guangxia; Yoon, Sun Hee; Cha, Hyun Gil; Han, Dong Suk; Park, Hyunwoong ( Royal Society of Chemistry , 2022 , Article)The electrocatalytic hydrogenation of 5-hydroxymethylfurfural (HMF) to 2,5-bis(hydroxymethyl)furan (BHMF) is an alternative to conventional heterogeneous catalysis with H2 at high temperatures and pressures. Although Ag ... -
