Importance of the Relationship between Surface Phases and Photocatalytic Activity of TiO 2

The junction boosts the function: With a combination of surface-sensitive techniques, the photocatalytic activity of TiO2 was found to be directly related to the surface-phase structure, and can be greatly enhanced when anatase TiO2 nanoparticles are highly dispersed on the surface of rutile TiO2 to form anatase–rutile surface-phase junctions (see picture for calcination progression).
