摘要：

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 mug 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.
