Photomicroreactor

A photomicroreactor is a miniaturized photoreactor for carrying out photochemical or photo- catalytic reactions. Due to its design, the photomicroreactor belongs to microreaction technology . The size of the reaction space of the photomicroreactor is in the micrometer range. A photomicroreactor thus has all the advantages and disadvantages of microreaction technology. The photomicroreactor essentially consists of two components: the reaction chamber and a light source. Various requirements are placed on the reaction space. For homogeneous photocatalysis, a suitable design of the reaction space must allow a sufficiently large layer thickness for high absorption of the incident light according to Lambert-Beer’s law . Reaction spaces for the heterogeneous photocatalysis are more complicated in their construction, since a catalyst in the solid aggregate state has to be introduced.
