Hee Yoon Roh, Ki-Yong Yoon, Jaehoon Jeong, Kyung-Bok Lee, Dohyung Kim, Yangdo Kim, Juchan Yang
Korean J. Met. Mater. 2025;63(2):168-176. Published online 2025 Feb 5 DOI: https://doi.org/10.3365/KJMM.2025.63.2.168
Abstract
Water splitting is a sustainable method of hydrogen production that is crucial for achieving carbon neutrality. However, the high cost of green hydrogen remains a major challenge. One strategy to reduce costs is the use of non-precious metal catalysts, such as Co, which is known for its excellent catalytic properties...... More

Korean J. Met. Mater. 2020;58(1):49-58. Published online 2019 Dec 12 DOI: https://doi.org/10.3365/KJMM.2020.58.1.49
Abstract
In this study, we investigated the morphological, crystal structural, electronic structural, and electrocatalytic properties of the inverse spinel structured copper cobalt oxide (Cu 0.72Co 2.28O 4) catalysts. The materials were prepared by coprecipitation using various copper and cobalt precursors, and subsequent oxidation treatment. Electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Brunauer Emmett..... More
