Photocatalytic properties of Cu negative-ion implanted TiO2 (rutile) were investigated as well as light absorption properties due to surface plasmon resonance of Cu nanoparticles in TiO2. Cu negative ions were implanted into TiO2 at 50 keV and also catalytic efficiencies were measured by decolorization method of methylene blue solution. After thermal treatment at 400°C, implanted sample showed an optical absorption peak at a photon energy 1.9 eV. This photon energy of absorption peaks well agreed with an estimate value of surface plasmon resonance calculated by Mie's theory with n = 2.71. In the catalytic test with methylene blue under irradiation of a fluorescent light, Cu-implanted rutile (50 keV, 7 × 1016 ions/cm2, 400°C annealed) showed 1.8 times the catalytic efficiency of the unimplanted rutile.
