摘要：

(Figure Presented) 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). © 2008 Wiley-VCH Verlag GmbH & Co.
