Abstract

A family of Cu/TiO₂ catalysts was prepared using a refined sol–gel method, and tested in the photocatalytic reduction of CO₂ by H₂O to CH₄ using a stirred batch, annular reactor. The resulting photoactivity was benchmarked against pure TiO₂ nanoparticles (synthesised by an identical sol–gel route). CO₂ photoreduction exhibited a strong volcano dependence on Cu loading, reflecting the transition from 2-dimensional CuOx nanostructures to 3-dimensional crystallites, with optimum CH₄ production observed for 0.03 wt.% Cu/TiO₂.
