A bar diagram of HER overpotentials of Ni(OH)2 (purple) at 16 mA cm−2 in 1 M KOH with various catalytically enhancing (green) and poisoning (red) metal ions and also with metal ions (blue) that had played no significant role in changing its HER activity. All these values were taken from the study of Corrigan and Bendert.[80]
