Anchoring Ru nanoclusters to defect-rich polymeric carbon nitride as a bifunctional electrocatalyst for highly efficient overall water splitting

The Ru nanoclusters anchored in defect-rich g-C 3 N 4 with abundant V N were successfully prepared by one-step pyrolysis. The cooperation of defect engineering, size effect and synergistic effect endows the Ru NCs/V N -C 3 N 4 excellent HER and OER activity.
