In-situ spectroelectrochemical study of highly active Ni-based foam electrocatalysts for hydrogen evolution reaction

Green hydrogen is a valuable energy source able to overcome the environmental issues generated by fossil fuel consumption. In this regard, large-scale production of green hydrogen could be achieved by anion exchange membrane water electrolyzer (AEMWE). However, highly electroactive, and low-cost catalysts for hydrogen evolution reaction (HER) are critical to executing AEMWE. With this end in view, a straightforward route is revealed to improve the catalytic performance toward the HER of commercial and low-cost Ni foam electrodes.
