The CuO (0 0 2 and 1 1 1 plane) peaks at 2{theta}=35.50 and 38.73 appeared with above 5 mol% loaded TiO{sub 2}. The CuO component (Cu2p{sub 3/2}) at 933.5-934 eV was shown in the XPS band of the Cu/TiO{sub 2} photocatalysts, which increased in size with increasing amount of loaded Cu. All of Ti2p{sub 3/2} bands for Cu/TiO{sub 2} appeared at 458.8 eV, which were assigned to Ti{sup 4+}, most likely due to pure TiO{sub 2}. The measured full widths at half maximum (FWHM) of the Ti2p peaks for Cu/TiO{sub 2} were larger compared to that of pure TiO{sub 2}; a larger FWHM implies a greater amount of less-oxidized metals. The ratios of metal-OH/metal-O in the O1s bands, which imply hydrophilicity, were increased in the Cu/TiO{sub 2} compared to pure TiO{sub 2}. The production of H{sub 2} from methanol/water photodecomposition was greater over the Cu/TiO{sub 2} photocatalysts than over the pure TiO{sub 2}; the production reached 13,500 {mu}mol after 10 h over 10 mol% Cu/TiO{sub 2}.
