Abstract:The detection limit of Rh(1) in the Rh/Al2O3 catalyst in a form of Rh1(CO)2 was determined by FTIR spectroscopy. It was demonstrated that at least 0.5 mgrg Rh, corresponding to 0.005 wt% of Rh, can be identified in this way. During synthesis gas conversion the predominant surface species is Rh x -CO, but a detectable amount of Rh(1) exists on the catalyst up to 473 K.This laboratory is a part of the Center for Catalysis, Surface and Material Science at the University of Szeged.
Keywords:Detection of Rh(1)  supported Rh catalyst  structural changes of Rh cluster  syngas reaction over Rh  alcohol synthesis  infrared spectrum of adsorbed CO
