RESUMO
The data presented in this article are related to the research article entitled: "Electrochemical characterization of Raney nickel electrodes prepared by atmospheric plasma spraying for alkaline water electrolysis" (Kim et al., 2018). This article describes the characterization of raw Ni-Al alloy and Raney Ni powders via X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS), and presents the EDS data of the prepared electrodes.
RESUMO
In this study, microstructures of Cu powders coated with octanethiol were analyzed using (scanning) transmission electron microscopy. Moreover, aging process of the octanethiol-coated layer as time passes by was analyzed using the electron energy loss spectroscopy technique. The octanethiol layer coated on the surface of Cu powders was kept until it was exposed to air for around 30 days. As days passes by, the coating layer had been decomposed and then a Cu(2)O layer was formed on the surface of powders.
