Abstract

A series of metallic copper (Cu)-decorated microsized, nanoporous titanium dioxide (TiO₂) materials with different loadings of Cu were synthesized by in situ hydrolysis of Sn²⁺-grafted titanium glycolate microspheres in the presence of Cu²⁺ ions. The resulting materials showed good photocatalytic activity for CO₂ reduction with water. In particular, the material prepared with an optimal loading of Cu (≈0.4 wt %) exhibited the highest photocatalytic activity for the reduction of CO₂ to hydrocarbon fuel (CH₄), with an efficiency that was 21-fold higher than that of the most commonly studied and utilized commercial photocatalyst, Degussa P25 TiO₂, under similar reaction conditions.
