摘要

The direct photoreduction of CO2 via catalytic conversion of copper supported on TiO2 based monolithic structures is a means by which solar fuels can be produced. Copper based monolithic structures with varying loadings were synthesized through a sol-gel dip coating procedure and tested for CO2 reduction with H2O as a reductant in the gaseous phase. Results established that increased copper concentration can decrease crystalline size and promote anatase to rutile phase transformation. The coated monolithic structures were dominated by mainly Cu~(1+) species, as confirmed by XPS while bulk characterization suggests that these species are present in the crystal lattice via substitution of Ti~(4+) ions with Cu~(1+) ions. The catalytic performance of the Cu doped TiO2 monoliths for hydrocarbon formation was found to be considerably higher when compared to pure TiO2 under UVA or visible light irradiation.
