초록 | Copper-doped titanium dioxide materials with anatase phase (Cu-TiO 2 , atomic Cu contents ranging from 0 to 3% relative to the sum of Cu and Ti), and particle sizes of 12-15nm, were synthesised by a solvo-thermal method using ethanol as the solvent and small amounts of water to promote the hydrolysis-condensation processes. Diffuse reflectance UV-vis spectroscopy show that the edges of absorption of the titania materials are somewhat shifted to higher wavelengths due to the presence of Cu. X-ray photoelectron spectroscopy (XPS) indicate that Cu(II) is predominant. Photocatalytic CO 2 reduction experiments were performed in aqueous Cu-TiO 2 suspensions under UV-rich light and in the presence of different solutes. Sulfide was found to promote the efficient production of H 2 from water and formic acid from CO 2 . The effect of the Cu content on the photoactivity of Cu-TiO 2 was also studied, showing that copper plays a role on the photocatalytic reduction of CO 2 . |
