Photocatalytic Performance of Ball-Milled Anatase/Rutile Mixed Phase TiO₂ Composite Powders

Abstract:

Mixed-phase anatase/rutile titanium dioxide (TiO₂) composite powder is an important material due to the unique properties of photocatalytic activity that is higher than that of the only single anatase or rutile phase. In this study, the anatase/rutile mixed phase TiO₂ composite powders were prepared by ball milling of TiO₂ commercial grade powders. Effect of the anatase/rutile phase ratio and milling time on photocatalytic performance were investigated. The sample phase ratio is evaluated using X-ray diffraction (XRD) meanwhile the composite morphology is characterized using field emission scanning electron microscope (FE-SEM). The overall results revealed that the mixed-phase anatase/rutile provided significant enhancement in photocatalytic performance comparing to only anatase or rutile single phase. In addition, this ball-milling technique is considered as an effective process and cost-effectively on energy saving suitable for preparing anatase/rutile mixed-phase TiO₂ for photocatalytic application.
