TL;DR: In this article, an interpretation of "splashes" is given, sharp long-living variations in reaction parameters, registered in a number of kinetic experiments, and the model of the simplest catalytic mechanism providing relaxation self-oscillations is used.

TL;DR: In this paper, the turnover number for ammonia synthesis was found to be smaller on very small iron particles than on larger ones, but it could be enhanced by a pretreatment which seemed to bring about a surface reconstruction induced by nitrogen.

TL;DR: In this article, it is shown that a broad variety of slow chemisorption steps can serve as buffer with the restriction that the buffer step should not, or at least only slightly, contribute to the surface reaction.

TL;DR: In this article, surface heterogeneity can induce sustained kinetic oscillations, when a simple, isothermal reaction occurs on a catalytic surface, and the proposed model demonstrates that these oscillations may occur for realistic values of surface heterogeneity.

TL;DR: In this article, the kinetics of ethylene and propylene oxidation over Rh and Ru supported on low area α-alumina were studied and found similar to those reported earlier for the same metals supported on high area silica.

TL;DR: The surface area of dispersed platinum on different supports has been measured by means of a "titration" technique involving the interaction between chemisorbed oxygen and carbon monoxide as mentioned in this paper.
