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 TiO2 was synthesised and successfully employed as a solar cell sensitizer. Furthermore, we demonstrated that the copper(I) dye-sensitised TiO2-based photocatalyst exhibits impressive effectiveness for the selective photoreduction of CO2 to CH4 under visible light.
