Photocatalytic Reduction of CO₂ on Au/TiO₂ Nanocomposite Film

Abstract:

Plasmonic Au decorated TiO₂ nanosheet film was firstly prepared by the combination of a hydrothermal method and a microwave-assisted chemical reduction process. The prepared sample was characterized by scanning electron microscopy (SEM), UV-vis absorption spectrum (UV-vis) and photoluminescence spectrum (PL) respectively. Results show that Au nanoparticles with narrow distribution are uniformly loaded on the nanosheet surface, and the resulted composite nanostructure exhibits distinct surface plasmon absorption and quenched photoluminescence compared to pure TiO₂ nanostructure. Photocatalytic tests show that Au decorated TiO₂ exhibits enhanced photocatalytic activity for photocatalytic reduction of CO₂ to methanol.
