3D WS sub(2) Nanolayers[at]Heteroatom-Doped Graphene Films as Hydrogen Evolution Catalyst Electrodes

A 3D catalyst electrode is fabricated by layer-by-layer assembly of 2D WS sub(2) nano-layers and P, N, O-doped graphene sheets into a heterostructured film. The film exhibits remarkable hydrogen evolution performance, benefitting from the utmost exposed active centers on 2D nanolayers, highly expand...

Zusammenfassung:A 3D catalyst electrode is fabricated by layer-by-layer assembly of 2D WS sub(2) nano-layers and P, N, O-doped graphene sheets into a heterostructured film. The film exhibits remarkable hydrogen evolution performance, benefitting from the utmost exposed active centers on 2D nanolayers, highly expanded surface, and continuous conductive network, as well as strong synergistic effects between the components.
