A copper(I) dye-sensitised TiO2-based system for efficient light harvesting and photoconversion of CO2 into hydrocarbon fuel.

A new copper(I) complex with the ability to bind to TiO(2) was synthesised and successfully employed as a solar cell sensitizer. Furthermore, we demonstrated that the copper(I) dye-sensitised TiO(2)-based photocatalyst exhibits impressive effectiveness for the selective photoreduction of CO(2) to CH(4) under visible light.
