Heterogeneous Photocatalysis

The laboratory of heterogeneous photocatalysis is equipped to investigate the processes of waste gas purification with the use of photocatalytic methods. Gas mixture analysis is also done. The laboratory investigates photocatalyst efficiency in photocatalytic reduction of carbon dioxide (both liquid and gas phase), photocatalytic decomposition of nitrous oxide, photocatalytic cleavage of water in the presence of methanol and degradation of MTBE from water. We also investigate photocatalytic reaction kinetics and advanced oxidation processes for waste gas purification. The laboratory is equipped with batch photocatalytic reactors with different geometries for gas and liquid phase reactions, a flow photoreactor for gas phase decomposition reactions, a gas chromatograph (BID), a photo electrochemical spectrometer, a Kelvin probe and a pilot plant unit for investigating advanced oxidation processes. The laboratory also offers testing of powder photocatalysts for reactions in gas and liquid phases, of thin films for reactions in gas and liquid phases, as well as testing of photocatalytically active materials for gas phase reactions according to ČSN ISO 22197.
