Solar-Driven, Highly Stable Photocatalyst System for Mitigation of Organic Pollutants via Mixed Phase Titania

Part of the Green Energy and Technology book series (GREEN)


In most cases, the combination of both anatase (up to 80%) and rutile (up to 20%) structures in a mixed phase titania semiconductor resulted in a better photocatalytic performance compared to the pure phase. The improvement from anatase to rutile is brought about by the enhanced transportation of photo-generated electrons. This consequently results in improved efficiency of the photoelectric and photocurrent conversion. This chapter highlights the effects of the morphology, particle size, and crystal structure of the mixed phase titania toward the photodegradation of water pollutants. It was demonstrated that the synergistic effect between anatase and rutile titania due to the interfacial electron transfer from rutile to anatase improving the photocurrent, as well as the overall conversion efficiency of the anatase photo-anodes. The morphologies of mixed phase titania also contributed to the final photodegradation properties. The charge and electron transfer of mixed phase titania improved the one-dimensional structure. This consequently enables photodegradation at the visible light range.
