| Abstract: | N-doped TiO2 powder were prepared by sol-gel procedure using NH4NO3 as the nitrogen source and followed by calcination at certain temperature.The photocatalytic activity were evaluated by measuring the decomposition of methyl orange under UV irradiation.XRD and SEM were commanded to characterize crystal structure and morphology.The change of crystal structure was important influenced through additive nitrogen as well as the photocatalytic activity. |
