Abstract

(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).
