ABSTRACT
To exploit the benefits of nanostructuring for enhanced hydrogen evolution reaction (HER), we employed coaxial electrospinning to synthesize single-layered WS2 nanoplates anchored hollow nitrogen-doped carbon nanofibers (WS2@HNCNFs) as efficient electrocatalysts. For comparison, bulk powder and single layers embedded in (WS2@NCNFs) were synthesized electrochemically tested. The distinctive design WS2@HNCNFs enables remarkable electrochemical performances showing a low overpotential with reduced charge transfer resistance, small Tafel slope, excellent durability. experimental results highlight importance nanostructure engineering electrocatalysts HER.
