Abstract
To achieve net zero emissions, green hydrogen should be produced via water electrolysis with renewable energy. To develop efficient anion exchange membrane water electrolyzers (AEMWE), the development of efficient and stable non-precious metal electrocatalysts for the oxygen evolution reaction (OER) is essential. In this study, a high-performance ternary NiFeCo-layer double..... More

Abstract
In this study, we investigated the morphological, crystal structural, electronic structural, and electrocatalytic properties of the inverse spinel structured copper cobalt oxide (Cu0.72Co2.28O4) 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

DOI: https://doi.org/10.3365/KJMM.2018.56.12.885

Abstract
Molybdenum disulfide (MoS2) based electrocatalysts have been proposed as substitutes for platinum group metal (PGM) based electrocatalyst to hydrogen evolution reaction (HER) in water electrolysis. Here, we studied MoS2/CNFs hybrid catalyst prepared by electrospinning method with heat treatment for polymer electrolyte membrane(PEM) water electrolysis to improve the HER activity. The..... More
