文摘

The metal deposits obtained by chemical reduction were smaller than those by photoreduction. Pt0 and oxidized Pt species coexist on Pt-C and Pt-P. In both, Au-C and Au-P, gold in mainly found in zero oxidation state. Au-modified catalysts were more photoactive than Pt-modified catalysts under UV radiation. The incorporation of Pt and Au on the TiO2 increases its activity in the visible region.
