Description
Summary: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. Flow‐induced power generation from graphene‐water interface is investigated. Surface charge and hydrophilicity of graphene is tuned by nitrogen doping. Nitrogen‐doped graphene is shown to generate higher power compared with pristine grapheme.
