Effect of annealing atmosphere towards TiO2 nanoparticles on their photocatalytic performance in aquoues phase

Abstract

TiO2 is one of the most semiconductors metal oxides used in many applications covering various field such as optoelectronics, medicine, sensor devices and catalyst [1]. Such applications are depended strongly on the crystalline structure, morphology and particle size [2]. Among the common crystalline form of titania, anatase is proven to be excellent photocatalyst compared to rutile and brookite.
