Acetone chemistry on oxidized ad reduced TiO2(110)
Article Abstract:
The chemistry of acetone on the oxidized and reduced surfaces of TiO(sub 2)(110) is examined by using temperature programmed desorption (TPD) a high-resolution electron energy-loss spectroscopy (HREELS). The reduced surface is prepared with about seven percent oxygen vacancy sites by annealing in ultrahigh vacuum at 850 K and the oxidized surface is prepared by exposure of the reduced surface to molecular oxygen at 95 K.

Photooxidation of acetone on TiO2(110): Conversion to acetate via methyl radical ejection
Article Abstract:
Acetone photooxidation on TiO2(110) is shown to involve a thermal reaction between acetone and an adsorbed oxygen species to form an acetone-oxygen complex. This complex photodecomposes via photogenerated charge carriers in the substrate through a mechanism involving methyl radical ejection from the surface and conversion of the complex to surface bound acetate.
