Mineral dust and other metal-containing aerosols play an important role in multiphase and heterogeneous atmospheric processes.  Semiconductor photocatalysis and transition metal catalysis are important in hydroxyl radical oxidation chemistry and sulfate formation in the atmosphere.  In this talk, I will discuss some recent studies laboratory studies to determine reaction mechanisms and kinetics of these different processes.  These will include studies that focus on determining new mechanisms for sulfate formation and addressing the question – does cyclohexane oxidation from titanium dioxide photocatalysis occur on the surface or in the gas phase?     <br/>
