Abstract
Nitrogen-doped TiO2 (TiO2 N) nano-particles with a pure anatase crystalline structure were successfully synthesized through the hydrolysis of TiCl4 in an ammonia aqueous solution. The samples were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), N-2-sorption, and UV-vis diffuse reflectance spectra (UV-vis DRS) techniques The absorption edge of nitrogen-doped TiO2 shifted into the visible wavelength region. The photoelectrochemical (PK) performances were investigated for the TiO2 mesoporous electrodes doped with different nitrogen concentrations The TiO2 center dot N electrodes exhibited much higher PEC responses compared to the pure TiO2 electrode because of the significantly enhanced visible-photoresponsibility of the TiO2 N electrodes
