• Nanometer materials
• Photocatalytic activity
• Surface energy band structure
• Surface impregnation method

(Ag, Nd)/TiO2 nanometer materials and nano-TiO2 doped Nd element were prepared by surface impregnation method with the nitrate of Ag and Nd as precursors. (Ag, Nd)/TiO2 nanometer materials were characterized by ESR, UV-vis and STM/STS techniques. The results showed (Ag, Nd)/TiO2 nanometer materials appeared two sharp adsorption peak values in the range of 200 to 250 nm wavelength, and its absorbance was far beyond nano-TiO2 on UV wave band; it brought much higher intensity of active &middot OH arose substance appearing oxidation reaction by the irradiation of 355 nm ray; its surface energy had been greatly broadened, thus its photocatalytic activity was excellent on UV wave band.
