Abstract Electrocatalysts of the hydrogen evolution and oxidation reactions (HER HOR) are critical importance for realization future economy. In order to make electrocatalysts economically competitive large-scale applications, increasing attention has been devoted developing noble metal-free HER HOR especially alkaline electrolytes due promise emerging hydroxide exchange membrane fuel cells.
