Abstract

The photocatalytic fixation of CO ₂ to hydrocarbons was performed using LiNbO ₃. 0.126 cm ² of powdered LiNbO ₃ was irradiated with 64.2 mW/cm ² light from a mercury lamp with 10ml of water under 30% CO ₂/air. The LiNbO ₃ was held on a platen above the water to give a gas-solid catalytic reaction. Formic acid and formaldehyde were detected in the water after irradiation for 6 hours and produced at rates of 7.7 mmol and 1.1 μmol /hour. The calculated efficiency of the catalyst was calculated to be ca 2% which compared to 0.17% for TiO ₂ under the same conditions. MgO doped LiNbO ₃ was also tested and found to have an energy conversion efficiency of 0.72%.
