Insights into a rutile/brookite homojunction of titanium dioxide: separated reactive sites and boosted photocatalytic activity.

ABSTRACT: Benefiting from studies into Degussa TiO₂, forming junctions via combining different phases of a semiconductor may provide new insights into the design of efficient photocatalysts, which are a key element in current solar-driven fuel production and environmental remediation. In this work, we aimed at creating a highly efficient rutile/brookite homojunction through precise crystal phase control. Characterization of the morphology and structure revealed that the ultrafine brookite phase TiO₂ particles were uniformly attached to the surfaces of the rod-like rutile phase, not only readily forming a homojunction but also stabilizing the brookite phase. Surprisingly, the rutile/brookite-TiO₂ homojunction exhibited a synergetic effect, improving the photoca
