▎ 摘　　要

NOVELTY - Reducing graphene comprises preparing graphene oxide-titanium dioxide solution by mixing graphene oxide to a mixture of titanium dioxide and alcohol, and reducing graphene oxide by irradiating light on the mixture. USE - The method is useful for reducing graphene (claimed) for the manufacture of a thin film. ADVANTAGE - The method is capable of rapidly reducing the graphene with high reduction efficiency in an environmentally-friendly manner without degrading its physical properties.
