Photocatalytic fluidized bed reactor systems

A photocatalytic reactor system for performing chemical transformations in a fluid, the reactor system comprising:

• a fluidizable inorganic composite photocatalyst comprising a photoactive catalyst disposed on a non-photoactive material with a N2 BET surface area in the range from 50 to 600 m2/g and with attrition less than 3 wt %/h, the reactor system further comprising a photoreactor that contains the fluidizable inorganic composite photocatalyst, the reactor system further comprising an illumination source in a wavelength range of 250-420 nm that directs-photocatalytic illumination into the photocatalyst, the reactor system further comprising a mechanical means to fluidize the inorganic composite photocatalyst.
