Recent Progress on Low-Temperature Selective Catalytic Reduction of NOx with Ammonia
Autor: Eun Duck Park
Publikováno v: Molecules, Vol 29, Iss 18, p 4506 (2024)
Selective catalytic reduction of nitrogen oxides (NOx) with ammonia (NH3-SCR) has been implemented in response to the regulation of NOx emissions from stationary and mobile sources above 300 °C. However, the development of NH3-SCR catalysts active a

Recent Progress in Direct Conversion of Methane to Methanol Over Copper-Exchanged Zeolites
Autor: Min Bum Park, Eun Duck Park, Wha-Seung Ahn
Publikováno v: Frontiers in Chemistry, Vol 7 (2019)
The conversion of methane into an easily transportable liquid fuel or chemicals has become a highly sought-after goal spurred by the increasing availability of cheap and abundant natural gas. While utilization of methane for the production of syngas

Monitoring Transformations of Catalytic Active States in Photocathodes Based on MoSx Layers on CuInS2 Using in Operando Raman Spectroscopy
Autor: Sang Youn Chae, Noyoung Yoon, Oh shim Joo, Eun Duck Park
Publikováno v: Angewandte Chemie (International ed. in English).
The electrochemical activation of CuInS2/MoS x for photoelectrochemical (PEC) H2 production was revealed for the first time through in operando Raman spectroscopy. During the activation process, the initial metallic MoS x phase was transformed to sem

Partial oxidation of methane with hydrogen peroxide over Fe-ZSM-5 catalyst
Autor: Min Sik Kim, Eun Duck Park, Sung June Cho, Ki Hun Park
Publikováno v: Catalysis Today. 376:113-118
The effect of the catalyst preparation method on the catalytic activity of Fe-ZSM-5 for the partial oxidation of methane with H2O2 in an aqueous phase was examined. UV–vis spectroscopy and FT-IR spectroscopy after NO adsorption were used to charact

CuInS2 Photocathodes with Atomic Gradation-Controlled (Ta,Mo)x(O,S)y Passivation Layers for Efficient Photoelectrochemical H2 Production
Autor: Eun Duck Park, Sang Hyuk Im, Yoolim Kim, Oh-Shim Joo, Sang Youn Chae
Publikováno v: ACS Applied Materials & Interfaces. 13:58447-58457
An atomic gradient passivation layer, (Ta,Mo)x(O,S)y, is designed to improve the charge transportation and photoelectrochemical activity of CuInS2-based photoelectrodes. We found that Mo spontaneously diffused to the a-TaOx layer during e-beam evapor
