The photocatalytic activity was evaluated by the photodegradation of methylene blue under visible light. Its physicochemical properties were characterized by means of UV-Vis DRS, XRD, PT-IR, and XPS. The results indicated that N-B-TiO2 has good activity to the photodegradation of MB. Its decolourizing rate of methylene blue solution goes up to 98.4% under the visible light irradiation with 5 h. The doping nitrogen forms N-Ti-O and boron primarily existing in oxide appears in the N-B-TiO2 sample. They response for visible light of TiOa was also exploited.展开更多
