Abstract:The more sluggish kinetics of hydrogen evolution catalysts in base as compare to that in acid to some degree restricts hydrogen production performance of hydroxide exchange membrane electrolyzers, especially when using earth‐abundant catalysts. Here a ternary nickel–copper–molybdenum hydrogen evolution catalyst is reported that exhibits ≈5 times higher turnover frequency than without copper doping. The X‐ray absorption near‐edge structure and valence band spectrum demonstrate that the light doping of copper in… Show more
The sluggish Tafel kinetics and high noble metal usage of PtRu-based electrocatalyst in hydrogen evolution reaction (HER) are the key challenges for practical proton exchange membrane water electrolyzer (PEMWE). Here,...
