Electrospun three dimensional Co/CoP@nitrogen-doped carbon nanofibers network for efficient hydrogen evolution

Co and CoP nanograins embedded in porous nitrogen-doped carbon nanofibers (Co/CoP@NC) are prepared by a controllable electrospinning method and subsequent thermal treatments. This tailored Co/CoP@NC nanostructure demonstrates high electrocatalytic activity and stability towards hydrogen evolution over wide-pH ranges.394
