Nitrogen doped TiO2 photocatalyst prepared by low energy N+ implantation technique [link]Paper  abstract   bibtex   
A nitrogen doped TiO2 as a visible-light response photocatalyst was prepared by low energy N+ implantation technique. N+ -implanted TiO2 samples promoted the photocatalytic activity for degradation of methylene blue under visible-light irradiation. N 1s XPS and N K-edge XANES spectra of the photocatalytically active sample indicated that N replaces the O sites near the surface, whereas in the inactive samples N-O species are formed. We also found that the nitrogen concentration of the sample implanted with small amount of N+ (1 × 1021 m -2) is a little higher than that with large amount of N+ (3 × 1021 m-2). In the low energy (5 keV) N+ implantation, the sputtering of the sample atoms would be one of the important processes for controlling both the concentration and chemical state of the doped nitrogen.
