▎ 摘  要

NOVELTY - A core-sheath graphene fiber composite photoelectrode comprises a graphene fiber coated with a polymer gel electrolyte as an inner electrode, and a graphene/hydrogenated titanium dioxide nanorod fiber as an outer electrode. The outer electrodes are tightly wound around the inner electrode. USE - Core-sheath graphene fiber composite photoelectrode is used in solar energy conversion and photocatalytic degradation of organic waste gas. ADVANTAGE - The core-sheath graphene fiber composite photoelectrode has excellent conductivity, photoelectric conversion efficiency, visible light activity and flexibility, and can be prepared by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of core-sheath graphene fiber composite photoelectrode, which involves preparing a graphene oxide aqueous solution with concentration of 10-20 mg/ml, injecting into a coagulation bath, naturally drying, obtaining graphene oxide fiber, reducing, obtaining a graphene fiber, coating the graphene fiber with the polymer gel electrolyte, obtaining the graphene fiber coated with polymer gel electrolyte, adding graphene oxide fiber to a mixed solution of butyl titanate, deionized water and hydrochloric acid in a reactor, modifying titanium dioxide nanorods on surface of the graphene fiber by hydrothermal reaction, washing, drying in hydrogen/argon atmosphere, obtaining the graphene/hydrogenated titanium dioxide nanorod fiber, and tightly winding resultant graphene fiber coated with polymer gel electrolyte, and graphene/hydrogenated titanium dioxide nanorod fiber.
