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 […]

New Nickel Foam Catalyst Splits Water

August 2, 2017 | 2 Comments

Rice University scientists have developed a new single, robust catalyst that splits water into hydrogen and oxygen with Earth-abundant materials that approach the efficiency of more expensive platinum. The electrolytic film produced at Rice and tested at the University of Houston is a three-layer structure of nickel, graphene and a compound of iron, manganese and […]
