System for the photocatalytic degradation of volatile organic compounds

  • Summary:

    A system for investigation of photocatalytic degradation of volatile organic air pollutants. The system comprises a photoresistor designed to make use to the maximum extent of the active surface of the photocatalyst and light used for activation of this catalyst. The system offers the measurement of reaction temperature, intensity of light of the used lamps as well as thermostating the process due to use of a simple lamp cooling system. The use of an in-house constructed reflector in this system improves maximally the effectivity of utilizing the light for the photocatalytic tests.
