The development of flexible and binder free electrocatalytic materials based on low cost metal dichalcogenide and low weight carbon nanofibers (CNF) has been materialized as an effective strategy for the fabrication of advanced super light portable, wearable, and stretchable sensor devices. In this work, the NiP2/hollow N-doped nanocapsules decorated nitrogen-doped carbon nanofiber (NiP2/CNCNF), have been designed for the first time. The NiP2/CNCNF was used directly as a flexible and freestanding electrode toward electrocatalytic and nonoenzymatic glucose sensing. The NiP2/CNCNF displayed high conductivity, flexibility with low weight, excellent electrochemical activity, steadiness and enhanced electron transfer rate.
