- •
Holey graphene monoliths (Nr-HGM) with the nitrogen content close to the theoretical upper limit.
- •
Nr-HGM were fabricated via supramolecular assembly of dicyandiamide induced by ammonium sulfate.
- •
Nr-HGM showed high porosity and high surface area .
- •
Nr-HGM showed excellent alkaline HER activity, surpassing other metal-free carbon catalysts.
