	abstract = {The photocatalytic decompn. of cortisone 21-acetate (CA), a model compd. for the commonly used steroid, cortisone, was studied.  CA was photocatalytically decompd. in a slurry reactor with the initial rates 0.11-0.46 mg/L-min at 10 mg/L concn., using the following heterogeneous photocatalysts in decreasing order of their catalytic activity: ZnO > Evonik TiO2 P25 > Hombikat TiO2 > WO3.  Due to the lack of ZnO stability in aq. solns., TiO2 P25 was chosen for further expts.  The decompn. reaction was found to be pseudo-1st order and the rate const. decreased as a function of increasing initial CA concn.  Changing the initial pH of the CA soln. did not affect the reaction rate significantly.  The decompn. reaction in the presence of the oxidizing sacrificial agent Na persulfate showed an obsd. decompn. rate const. of 0.004/min, lower than that obtained for TiO2 P25 (0.040/min).  The highest photocatalytic degrdn. rate const. was obtained combining both TiO2 P25 and S2O82- (0.071/min) showing a synergistic effect.  No reactive intermediates were detected using LC-MS showing fast photocatalytic decompn. kinetics of CA. [on SciFinder(R)]},

	abstract = {Several remarkable observations regarding structure, (surface) compn. and visible light induced photocatalytic activity of Bi-promoted anatase photocatalysts are reported.  First, XPS characterization data show that compns. of mixed Bi-Ti-oxide phases obtained by hydrothermal treatment at 180{\textdegree} 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. [on SciFinder(R)]},
