Comunicación a congresoIn this work, it has been synthesized several Au and Au-Cu alloy photocatalysts supported on two
different mesoporous supports: a non-commercial SBA-15 and a post-synthesis TiO2 modified SBA-15
(TiSBA-15), with which a high dispersion of TiO2 species have been achieved maintaining the SBA-15
structure. In addition, it has also been obtained highly dispersed Au nanoparticles confined in SBA-15
pore channels, as can be observed in Figure 1. The photocatalysts have been preliminary tested in the
preferential CO oxidation in a H2-rich stream (CO-PROX) at room temperature and atmospheric pressure
under simulated solar light irradiation. In spite of the very low gold and copper loading (1.5 wt% and
0.5wt% respectively), the catalysts resulted active and selective in the low temperature photo-CO-PROX.Universidad de Málaga, Campus de Excelencia Internacional Andalucía Tec
