description | Institut français du pétroleThe diffuse reflection infrared Fourier transform spectroscopy (DRIFTS) technique, less practiced than the transmission mode because of its limitations, is extremely useful, indeed indispensable, for non-transparent materials and/or for in situ measurements at elevated temperature. The authors describe the principles of this technique and its advantages over transmission infrared spectroscopy. The application of DRIFTS to the characterization of catalysts is illustrated by two studies conducted on the interaction of molybdenum with the precursor of fuel desulphurization catalysts, and on the in situ modifications under reactive gases of catalysts for reducing nitrogen compounds in exhaust gases.
La technique infrarouge de spectroscopie de réflexion diffuse (DRIFTS), moins pratiquée que la transmission en raison de ses limitations, est extrêmement utile, en effet indispensable, pour les matériaux non transparents et/ou pour des mesures in situ à la température élevée. Les auteurs décrivent les principes de cette technique et ses avantages par rapport à la spectroscopie infrarouge en transmission. L'application de DRIFTS à la caractérisation des catalyseurs est illustrée par deux études : sur l'interaction du molybdène avec le précurseur de catalyseurs de désulfuration de carburant, et sur les modifications in situ sous gaz réactifs des catalyseurs de réduction des composés azotés dans les gaz d'échappement. |
