- Abstract
Nitrogen-doped nano-sized titania N-TiO2 photocatalysts were prepared by sol-gel process followed by ultrasonication.The photocatalytic decomposition of methyl orange in aqueous solution was used as a probe reaction to estimate their photocatalytic activities.Applying means of XRD,TEM and UV-Vis DRS and XPS,we analyzed the crystallite sizes,the cystal pattern,the optical property of TiO2 samples. The synthesized N-TiO2 nanocrystals are catalytically active and absorb well into the visible region up to 600 nm.N-TiO2 showed high degradation of methyl orange under ultraviolet as well as visible light irradiation since it has small grain,wide dispersion and strong visible-light absorption.
