Abstract

Photocatalytic reduction of CO₂ into valuable hydrocarbons using TiO₂ is a promising route for mitigating the effects of global warming and meeting future energy demands. However, TiO₂ utilises UV light for photocatalysis and its hydrocarbon yields are still low. In order to enhance the light absorption and increase yields, light-harvesting complexes (LHCII) extracted from spinach were attached to the surface of Rh-doped TiO ₂ (TiO₂:Rh) resulting in a hybrid catalyst, TiO ₂:Rh-LHCII. The LHCII can absorb visible light in green plants, which convert CO₂ to sugars via photosynthesis. CO, acetaldehyde and methyl formate were produced from aqueous CO₂ solution in a stirred batch reactor under visible-light irradiation. The yields of acetaldehyde and methyl formate were enhanced by almost ten and four times respectively, when using TiO₂:Rh-LHCII compared to those of TiO₂:Rh.
