A step forward for tungsten : Nitrogen‐rich tungsten carbonitride (WCN) nanomaterials can act as stable and efficient hydrogen evolution electrocatalysts with a much higher activity than conventional WCN materials. The use of a polymerization process provides a unique synthetic route to H 2 WO 4 nanoparticles, which can then be used to synthesize the WCN‐derived catalysts.
