Au-Decorated Ce-Ti Mixed Oxides for Efficient CO Preferential Photooxidation.

ABSTRACT: We investigated the photocatalytic behavior of gold nanoparticles supported on CeO₂-TiO₂ nanostructured matrixes in the CO preferential oxidation in H₂-rich stream (photo-CO-PROX), by modifying the electronic band structure of ceria through addition of titania and making it more suitable for interacting with free electrons excited in gold nanoparticles through surface plasmon resonance. CeO₂ samples with different TiO₂ concentrations (0-20 wt %) were prepared through a slow coprecipitation method in alkaline conditions. The synthetic route is surfactant-free and environmentally friendly. Au nanoparticles (<1.0 wt % loading) were deposited on the surface of the CeO₂-TiO₂ oxides by deposition-precipitation. A benchm
