%X A High Throughput (HT) approach is used to prepare and characterize the catalytic activity of materials for the destruction of Volatile Organic Compounds (VOC) at low temperature. The interest of the Designs of Experiments (DoE) in the primary screening is demonstrated through modeling catalysts composition according to the light-off temperature detected by infrared thermography. The combination of the mass spectrometry and the infrared thermography appears very useful to confirm and increase information about catalytic properties of the catalysts extracted to the primary screening stage. Finally, in situ Raman spectroscopy with infrared thermography allows to better understand the origin of the catalytic properties in the case ofAu/CeO2 catalysts. A strong interaction between gold and Ce-O bonds leading to an improvement of the cerium oxide reducibility could explain its high reactivity for 2-propanol oxidation at lower temperature. Une approche haut debit (HD) est utilis¨¦e de la pr¨¦paration jusqu¡¯¨¤ la caract¨¦risation de l¡¯activit¨¦ catalytique des mat¨¦riaux pour l¡¯¨¦limination des Compos¨¦s Organiques Volatils (COV) ¨¤ basse temp¨¦rature. L¡¯int¨¦r¨ºt des plans d¡¯exp¨¦riences (DoE, en anglais Designs of Experiments) dans le screening primaire est d¨¦montr¨¦ grace ¨¤ l¡¯identification d¡¯une composition optimale de catalyseur pr¨¦dite ¨¤ l¡¯aide des diff¨¦rentes temp¨¦ratures d¡¯ignition des catalyseurs obtenues par thermographie infrarouge. La combinaison in situ de la spectrom¨¦trie de masse et de la thermographie infrarouge s¡¯est av¨¦r¨¦e d¡¯une grande utilit¨¦ pour confirmer et augmenter le niveau d¡¯information concernant les propri¨¦t¨¦s catalytiques des catalyseurs provenant du screening primaire. Enfin, la spectroscopie Raman in situ coupl¨¦e ¨¤ la thermographie infrarouge permet de mieux comprendre l¡¯origine des propri¨¦t¨¦s catalytiques dans le cas du catalyseur Au/CeO2. Une forte interaction entre les particules d¡¯or et des liaisons Ce-O, impliquant une augmentation de la r¨¦ductibilit¨¦ de l¡¯oxyde de c¨¦rium, pourrait expliquer son importante r¨¦activit¨¦ vis-¨¤-vis de l¡¯oxydation de l¡¯isopropanol ¨¤ plus basse temp¨¦rature.
