Novel One-dimensional Cu@C Nanofibers: Direct Solid-State Synthesis and Applications in Electrocatalytic Water Splitting

Encapsulating metal nanoparticles with graphitic carbon shell to remit the loss of active sites has drawn attention in catalysis. Herein, we report the development of a facile strategy to prepare graphitic carbon encapsulated Cu nanoparticles (Cu@C) nanofibers by in situ pyrolysis of organic-layered copper hydroxides, which exhibited superior activity and durability for electrocatalytic water splitting.
