Abstract

Graphene oxide/core–shell structured TiO₂@TiO_2−x nanocomposites with outstanding photocatalytic performance were prepared by combining graphene oxide and black titania. Ti³⁺ and graphene oxide as a mediator of electron transfer were introduced into the compounds, which strongly enhanced visible-light absorption and photocatalysis.
