Article summary:
1. Research on the electrochemical hydrogen evolution reaction (HER) is important for realizing a sustainable and economically feasible hydrogen-based economy.
2. The understanding of HER in alkaline media is limited due to lack of systematic studies on surfaces other than Pt in a broad pH window, and sole focus on the hydrogen adsorbed on the metal surface as the key descriptor for HER.
3. Non-covalent interactions between water molecules and alkali metal cations have been shown to play a significant role in determining the HER activity by locally interacting with the reactants/products of HER.
