CA 2622487
The invention concerns a method for detecting and/or testing and/or capturing at least one type of aldehyde, preferably formaldehyde, consisting in bringing a gas stream into contact with a material comprising a nanoporous metal oxide sol-gel matrix, which contains at least one probe molecule exhibiting at least one reactive function reacting with at least one aldehyde function. A material for carrying out said method, a method for producing the inventive material and sensors integrating said materials are also disclosed.
Procédé de détection et/ou de dosage et/ou de piégeage d'au moins un aldéhyde, préférentiellement le formaldéhyde, comprenant une étape de mise en contact d'un flux gazeux avec un matériau comprenant une matrice nanoporeuse sol-gel d'oxydes métalliques, ladite matrice contenant au moins une molécule sonde portant au moins une fonction réactive pouvant réagir avec une fonction aldéhyde, matériau pour sa mise en AEuvre, son procédé de préparation, et capteurs intérant de tels matériaux.
