New insight into binary TiO@C nanocomposites: the crucial effect of an interfacial microstructure.

Combining with carbon materials is a common and efficient strategy to improve the photocatalytic performance of TiO. But the fundamental nature of the interfacial microstructures between carbon and TiO and how they affect the photocatalysis process remain controversial. In this work, hybrid TiO@C nanocomposites with different carbon contents are synthesized.
