▎ 摘 要
NOVELTY - Producing octahedral transition metal dichalcogenides involves forming transition metal layer on substrate and injecting chalcogenide-containing gas onto the substrate together with plasma treatment. USE - Method for producing octahedral transition metal dichalcogenides, ADVANTAGE - The method enables to produce octahedral transition metal dichalcogenides that provides improved properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a electrode for hydrogen evolution reaction (HER), which comprises octahedral transition metal dichalcogenides.
