In situ IR spectroscopy for developing catalysts and catalytic processes

The role of in situ IR spectroscopy to characterize the surface of solid catalysts and to assess sorbed reactants and products together with important intermediates of the catalyzed reactions is outlined. Strategies are discussed using a complex case study, the synthesis of alkylamines. The experimental realization asks for the ability to record IR spectra in situ at elevated temperatures and pressures without influencing the kinetics of the reaction. On the advent of radically new methods of catalyst development, it is shown how IR spectroscopy will significantly contribute to catalyst and process development
