Flow microreactors are promising devices for screening photocatalyst
activity due to reaction times in the range of minutes compared to
several hours in conventional photoreactors and the ease of connection
to inline analytical techniques. A microfluidic platform which consists
of parallel microreactors and a rotating multi-wavelength LED light
source was developed and its operation was automated. The microreactors
were manufactured by 3D printing, the photocatalysts were immobilized as
thin films, and the photocatalytic activity was investigated by
applying successively various illumination conditions. The microfluidic
platform was used for screening the activity of TiO2-based
photocatalysts for degrading organic pollutants (e.g. imidacloprid,
phenol).
