Three-dimensional (3D) nitrogen(N) and sulfur(S) co-doped nanoporous graphene with preserved high conductivity was successfully synthesized by the assistant professor, Yoshikazu Ito and professor, Mingwei Chen at Advanced Institute for Materials Research, Tohoku University. The 3D NS-doped nanoporous graphene is constructed by a few layer graphene sheets that are continuously inter-connected to form a complex 3D network structure. Due to the nitrogen and sulfur co-doping and abundant nanoporous structures, the catalysis towards hydrogen evolution reaction has been successfully activated inside and outside the nanoporous graphene at absence of any metal catalysts. This hydrogen harvesting technology with 3D metal-free graphene catalyst shows a great promise for achieving economic hydrogen energy at high efficiency for green energy innovation.
