Preparation,characterization of N,P codoped TiO2 nanoparticles with their excellent photocatalystic properties

摘要：

Phosphor and nitrogen co-doped titania were prepared by hydrothermal method with phosphorous acid and ammonia as the P and N sources,respectively.The resulting materials were characterized by X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS).Phosphor and nitrogen co-doped titania give a higher photocatalytic activity in the degradation of methylene blue (MB) under solar light irradiation.It was evidenced that the incorporation of P and N in the anatase titania lattice in the form of O-Ti-N,O-P-N,and Ti-O-P linkages.After photocatalytic properties studies,we can conclude that N,P codoped titania exhibit the further enhanced photocatalytic activity.
