The hydrogen evolution reaction (HER) undergoes large overpotentials for achieving preferable efficiency due to its sluggish dynamics. As such, highly active electrocatalysts are often needed for its acceleration. Despite the significant progress achieved on the synthesis of transition‐metal (TM)‐based HER electrocatalysts, their activity is still far from their Pt‐based counterparts. In their Minireview article on page 3930 ff., C. He et al. describe current methods used for doping nonmetals into transition‐metal (TM)‐based nanomaterials and their performances in the HER. Doping nonmetals can efficiently tune the electronic structures of the TM and, therefore, optimize the Gibbs free energy of the TM for adsorption of H* intermediates, in turn boosting the HER of the TM.
