Advanced Fabrication of Chemically Bonded Graphene/TiO Continuous Fibers with Enhanced Broadband Photocatalytic Properties and Involved Mechanisms Exploration.

In this article, a novel route for the synthesis of graphene/TiO continuous fibers (GTF) using force-spinning combined with water vapor annealing method is reported for the first time. The morphology, structure and optical properties of the composite were fully characterized. With a single step of heat treatment process using steam at ambient conditions, we were able to initiate a series of chemical reactions, such as reduction of graphene oxide (GO), crystallization of TiO, formation of C-Ti bond, and introduction of oxygen vacancies into TiO.
