First, XPS characterization data show that compns. of mixed Bi-Ti-oxide phases obtained by hydrothermal treatment at 180° C of aq. solns. of ethanol, titanium n-butoxide, and bismuth nitrate, are surface enriched with a specific fraction of metallic-like bismuth.  Second, the formation of highly dispersed nanoparticles of platinum on these composites by photodeposition is accompanied by significant morphol. changes.  Third, the platinum functionalized, bismuth-promoted Anatase composites exhibit extraordinary photocatalytic activity in the photocatalytic degrdn. of org. compds. (Acid orange 7 and salicylic acid, resp.) upon illumination at 447 nm, higher than obsd. for P25 upon UV illumination in similar reactor configuration.  An optimized Pt-Bi-Ti-O composite consists of 1 wt% Pt and 5 wt% Bi.  The high activity of the composite is discussed on the basis of the cryst. morphol. and surface compn.
