Abstract:

Three areas have been investigated application of esr spectroscopy and time-resolved reflectance absorption and emission spectroscopy to establish mechanisms in photocatalytic oxidative degradations of organic molecules exploration of controlled oxidation chemistry for new heteroatom-containing organic molecules and synthesis and characterization of new quantized semiconductor-support systems. The objectives of this project have been largely accomplished despite discontinued funding of the parent grant beyond the initial nine months, instead of the requested three years. We have successfully demonstrated that photocatalytic oxidation on irradiated semiconductor surfaces is a useful route for degradation of various organic materials under constrained, highly controlled conditions.
