▎ 摘　　要

NOVELTY - A metal phosphide porous frame/graphene composite fiber is prepared by calcining a fibrous composite that is obtained by combining MOF crystal powder and graphene oxide as a precursor. USE - Metal phosphide porous frame/graphene composite fiber is useful in energy, environment or flexible device application (claimed) and as a cathode material for lithium ion batteries. ADVANTAGE - The metal phosphide porous frame/graphene composite fiber can be prepared in a simple manner under mild reaction condition, and has adjustable morphology, controllable structure and uniform component distribution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing metal phosphide porous frame/graphene composite fiber.
