▎ 摘　　要

NOVELTY - Preparation of graphene skeleton porous nanofiber comprises preparing water-soluble metal salt or metal oxide nanoparticles aqueous solution or suspension, adding water-soluble polymer while high-speed stirring to obtain spinning solution, electrospinning to obtain organic-inorganic composite nanofibers, high-temperature heating under inert atmosphere, taking out, and pickling. USE - Method for preparation of graphene skeleton porous nanofiber (claimed) used for energy storage, adsorption, sensing and filtration. ADVANTAGE - The method is simple, clean and environment-friendly, and has low cost. The product has intact structure of graphene.
