Performance of ultraviolet photocatalytic oxidation for indoor air applications: Systematic experimental evaluation

- An innovative experimental set-up was designed and constructed for testing UV-PCO.
- Test methodologies were developed to examine UV-PCO air cleaners for VOCs removal.
- VOCs type, inlet concentration, flow rate, irradiance, and RH have influence on PCO.
- Gas-phase ozonation with a variety of compounds was examined in a duct system.
- Formation of by-products generated from incomplete conversion was investigated.
