Time resolved vibrational spectroscopy and kinetics of (photo)catalytic reactions

Aim is to: 

• Understand the rate determining steps in photocatalytic conversions
• Liquid phase : Selective oxidation
• Gas phase : Selective oxidation including alternative oxidants,
  H₂S mediated chemistry, H₂O decomposition and CO₂ reduction
