A MINIATURIZED REACTOR FOR PHOTOCATALYSIS AND FOR SIMULTANEOUS IN SITU SPECTROSCOPY

The design of a miniaturized photoreactor is presented that allows for continuous as well as for stopped flow photochemical experiments on solid photocatalysts with gaseous educts. Volatile products can be analyzed by any gas phase detection scheme such as mass spectrometry or gas chromatography. In addition, the design allows for easy in situ optical spectroscopic measurements such as UV/VIS, IR, and luminescence, depending on the transparency of the window material used.
