Experimental and theoretical analysis shows that tungsten enhances interfacial water and lowers reaction barriers, improving HER.

The tungsten single-atom modifies the interfacial water structure and lowers the reaction barrier for hydrogen evolution.
This catalyst achieves an overpotential of just 76 mV at 10 mA cm−2 in alkaline conditions, indicating its high efficiency.
The atomic-level insights reveal how the electric field impacts water arrangement and HER kinetics significantly.
The W 1 O/NiS catalyst maintains 98% stability after 300 hours at a current density of 200 mA cm−2, showcasing its durability.

Cui et al. (2025) studied this question.
