摘要: The adsorption of CO at low temperatures (130–293 K) has been investigated on Rh/Al2O3 catalysts (0.001–1 wt%) Rh loadings by means Fourier transform infrared spectroscopy. surface structure produced different reduction (573 and 1173 was shock-cooled to 130 K, where the addition caused appearance band due bridge-bonded ((Rh0)2–CO) all samples. bands gem-dicarbonyl (Rh+(CO)2) linearly bonded (Rhx–CO) depended content temperature catalysts. positions integrated absorbances symmetric asymmetric stretchings Rh+(CO)2 changed with temperature. On basis above findings rearrangement adsorbed species (indirectly that Rh) is discussed.
