A clean N2-plasma was employed to develop self-supported porous tungsten nitride nanowires on carbon cloth (WN NW/CC) as an efficient 3D electrocatalyst for hydrogen evolution. The resulting catalyst gives a high activity and outstanding stability in both acidic and alkaline solutions.

A 3D-composite structure of FeP nanorods on vertically aligned graphene nanosheets has been fabricated for the high-performance hydrogen evolution reaction.

Novel 3D porous tungsten carbide hybrid nanowires (p-WCx NWs) are prepared on carbon cloth as a binder-free efficient electrocatalyst for hydrogen evolution. It shows a high activity and outstanding stability in both acidic and alkaline solutions.
