TL;DR: In this paper, the kinetics of the CO-O2 and CO-NO reactions over single crystal Rh(111) and over alumina-supported Rh catalysts have been compared at realistic reactant pressures.

TL;DR: In this paper, the interaction between Pt and Rh in three-way automotive catalysts was investigated by conducting laboratory reactor experiments with both a Pt Rh bimetallic catalyst (prepared by stepwise metal impregnation) and a physical mixture of Pt and rh monometallic catalysts while holding the absolute amount of each of the noble metals constant.

TL;DR: The inherent rate of the CO-O2 reaction over alumina-supported Rh is much higher than that of CO-NO reaction as mentioned in this paper, which indicates that the overall kinetic behavior of RhAl2O3 in CONOO2 mixtures is dominated by the features characteristic of the NO reaction rather than by those of the O2 reaction, which can be interpreted on the basis of a mechanism involving blocking of the reactive sites by molecularly adsorbed NO.

TL;DR: In this article, it was shown that the strongly-bound surface species present under the conditions of UHV studies are the same species reacting at high pressures for carbon monoxide oxidation and nitric oxide reduction over rhodium, and that high pressure rates can be predicted quantitatively using parameters determined solely under ultrahigh vacuum conditions.
