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

TiO
2
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.
