The PES-TiO2 optical absorption was determined by diffuse reflectance spectroscopy (DRS). By X-ray diffraction (XRD), the formation of TiO2 anatase on the PES surface was detected. The photocatalytic oxidation (PCO) of butyraldehyde and isovaleraldehyde was carried out in a batch photo-reactor equipped with a UV-mercury Philips 9W lamp and mediated by glass fiber GFT-TiO2 and PES-TiO2 surfaces. The removal of these two aldehydes was found to be a function of pollutant concentrations. The stable catalytic reuse of both catalysts reported. A Langmuir Hinshelwood (L-H) model describes the degradation kinetics on PES-TiO2 and on GFF-TiO2. The aldehyde degradation by-products were analyzed by gas chromatography mass spectrometry (GC-MS). Three organics intermediates identified during the aldehyde degradation were: acetones, alcohols and fatty acids. %G English %2 https://univ-rennes.hal.science/hal-01542761/document %2 https://univ-rennes.hal.science/hal-01542761/file/Innovative%20and%20stable%20TiO2%20supported%20catalytic%20surfaces%20removing%20aldehydes%20under%20UV.pdf %L hal-01542761 %U https://univ-rennes.hal.science/hal-01542761 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR-CIP %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MMS %~ TEST2-HALCNRS
