摘要：

A triple sequential junction by rationally combining anatase/rutile nanoparticle TiO2 heterophase (A(ns)/R) and rutile/rutile TiO2 homophase (R-ns/R) junctions was fabricated as a proof of concept. Such a continuous charge separation and transfer channel resulted in a remarkable enhancement in the separation of photogenerated carriers and the photocatalytic activity.
