Likewise, the various microwave photochemical and photocatalytic reactor types (batch with external or internal light source, flow-through with external light source, annular flow-through with internal EDL, and cylindrical flow-through surrounded with EDL) with different arrangement of the lamps are described.

Photochemical and photocatalytic degradation of diclofenac .

Photochemical and titanium dioxide (TiO2) photocatalysed degradations of diclofenac and amoxicillin in water, under natural and simulated sunlight, were investigated. Direct photolysis of diclofenac resulted in about 80% degradation after exposure to an irradiation level of 400 W/m2 for 4 h, while in the presence of TiO2, 96% of diclofenac was degraded after the same time period.

Photocatalytic reactions have been defined as those processes that require both a (not consumed) catalyst and light. A previous definition was whether such reactions brought a system towards or away from the (thermal) equilibrium. This consideration brings in the question whether a part of the photon energy is incorporated into the photochemical reaction products.
