Role of Doped Nitrogen in Graphene for Flow‐Induced Power Generation

Flow‐induced power generation using nanomaterials, for example, graphene–water interface, has become an attractive energy harvesting mechanism. The effect of heteroatom doping of graphene on flow‐induced electricity is investigated by the authors. Nitrogen‐doped graphene is shown to generate 1.5 times higher power compared with pristine graphene due to surface charges and increase in effective interfacial area. Thus, doping‐induced surface tuning of graphene enhances output performance. The flow‐induced power generation using doped‐graphene allows relaxing the material selection constraints in the triboelectric series.
