Graphene oxide/core-shell structured TiO2@TiO2-x nanocomposites with highly efficient visible-light photocatalytic performance

摘要

Graphene oxide/core-shell structured TiO2@TiO2-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.
