摘要：

Reassembling of exfoliated graphite oxide (GO) layers by contacting with titania clear sot gives a novel nanoporous composite of carbon nanosheets and functional titania nanoparticles, in which titania particles with an evident brookite structure or a mixed phases of anatase and brookite are encapsulated on the basal plane of and in between the inner surfaces of carbon nanosheets without aggregating together or depositing only on the edges of carbon nanosheets. These composites successfully combine properties of carbon nanosheets and titania nanoparticles. exhibiting an enhanced adsorptivity and a good photocatalytic activity toward organic dyes due to its unique structure, better porosity, and compatible surface affinity.
