Gold Alloyed With Nickel Studied For Hydrogen Production
August 23, 2023 | Leave a Comment
Chiba University researchers show the hydrogen evolution reaction activity of a GoldNickel/Gold electrocatalyst increases due to surface defects formed via Nickel dealloying. Gold (Au)-based electrocatalysts used for hydrogen production via water electrolysis exhibit high chemical stability but low hydrogen evolution reaction (HER) activity. Alloying them with nickel (Ni) can improve their HER activity. Now, a […]
