Korean J. Met. Mater. 2024;62(12):981-988.   Published online 2024 Nov 29
DOI: https://doi.org/10.3365/KJMM.2024.62.12.981

Abstract
Carbon materials used as an electrode for aqueous supercapacitors should be synthesized with a porous structure and hydrophilic properties to facilitate the adsorption and desorption of electrolyte ions for charge storage. To enlarge the specific surface area, the porous morphology should contain micropores (diameter < 2 nm). Mesopores (diameter: 2..... More

Sung Gue Heo, Sangwoo Kim, Seok-Jun Seo, Jae Jin Sim, Jiyeon Shin, Ali Mirzaei, Myung Sik Choi
Korean J. Met. Mater. 2000;62(8):631-638.   Published online 2024 Jul 31
DOI: https://doi.org/10.3365/KJMM.2024.62.8.631

Abstract
Nitrogen dioxide (NO2) is a highly dangerous gas, mostly emitting emitted from fossil fuels, and a major contributor to air pollution. It has negatively effects affects on the human health as well asand contributes to environmental issues like acid rain. In this study, mesoporous CuOx nanoparticles (NPs) were successfully synthesized..... More

Korean J. Met. Mater. 2022;60(8):577-586.   Published online 2022 Jul 12
DOI: https://doi.org/10.3365/KJMM.2022.60.8.577

Abstract
We fabricated a Li doped CuO photoelectrode by doping CuO with Li to improve the photoelectrochemical properties of the CuO photoelectrode. The fabricated Li doped CuO photoelectrode was optimized by experimentally investigating Li doping concentration, annealing temperature, and spin coating deposition cycle. It was confirmed that Li doped CuO had..... More

Korean J. Met. Mater. 2019;57(7):447-455.   Published online 2019 Jun 5
DOI: https://doi.org/10.3365/KJMM.2019.57.7.447

Abstract
In this study, a CuO buffer layer was deposited on a fluorine-doped tin oxide (FTO) substrate using a spin coating method, and then a CuO photoelectrode was grown on the CuO buffer layer using a modified-chemical bath deposition (M-CBD) method. We investigated the morphological, structural, optical, electrical and photoelectrochemical properties..... More
