김운기, 정재일, 이명진, 정보라, 예보라, 이희수, 김홍대
Korean J. Met. Mater. 2024;62(2):115-124.   Published online 2024 Jan 30
DOI: https://doi.org/10.3365/KJMM.2024.62.2.115

Abstract
Many studies have been conducted on methods to remove air pollutants. Among them, a representative commercial technology for reducing nitrogen oxides (NOX) is selective catalytic reduction (SCR) using NH3 as a reductant. However, the NH3-SCR technology has problems, such as the need for additional NH3 gas (Active-SCR), the fact that..... More

                
Fabrication of Ruthenium-Based Transition Metal Nanoparticles/Reduced Graphene Oxide Hybrid Electrocatalysts for Alkaline Water Splitting

Korean J. Met. Mater. 2023;61(3):190-197.   Published online 2023 Feb 24
DOI: https://doi.org/10.3365/KJMM.2023.61.3.190

Abstract
Green hydrogen has attracted significant attention as one of the future energy sources because no greenhouse gases are emitted during production and its energy density is much higher than fossil fuels. Precious metals such as platinum (Pt) and iridium (Ir)-based catalysts are commonly used for water splitting catalysts. However, because..... More

Korean J. Met. Mater. 2022;60(6):448-454.   Published online 2022 May 24
DOI: https://doi.org/10.3365/KJMM.2022.60.6.448

Abstract
Due to its high theoretical capacity in the conversion reaction, Co3O4, a transition metal oxide, has been attracting attention as an anode material for lithium-ion batteries. Comparing conventional slurry method with the electrophoretic deposition (EPD) method without additives (conductive agents and binders), we investigated the effect of the Co3O4/additive interface.....

Effects of Zn(BH<sub>4</sub>)<sub>2</sub>, Ni, and/or Ti Doping on the Hydrogen-Storage Features of MgH<sub>2</sub>
Myoung Youp Song, Young Jun Kwak
Korean J. Met. Mater. 2019;57(3):176-183.   Published online 2019 Feb 8
DOI: https://doi.org/10.3365/KJMM.2019.57.3.176

Abstract
In the present work, MgH2 was doped with Zn(BH4)2, Ni, and/or Ti to improve its hydrogen absorption and release features. Samples were prepared by grinding in a planetary ball mill in a hydrogen atmosphere. To increase the hydrogen absorption and release rates without significantly sacrificing hydrogenstorage capacity the additive percentages..... More
