The dimer-trimer model for heterogeneous catalysis

Time scaling in the reorganization of adsorbed species in surface reactions

“…In the case of surface reaction models, however, the phase diagrams show that the system can achieve steady-state situations characterizing separate reactive zones of the absorbing or poisoned sectors by irreversible phase transitions (IPTs) [3]. Among these models, the one that has accounted for the largest number of papers is the ZGB model [4], developed for the monomer-dimer (MD) reaction, between two components, of the "A + B 2 →" type, which mimics the oxidation of CO. Later, other authors have studied a series of similar models -for example, the monomer-monomer (MM) [4,5], the dimer-dimer (DD) [6], the monomer-trimer (MT) [7,8], and the dimer-trimer (DLT) [7][8][9].…”

Computational study of the dimer–trimer and trimer–trimer reactions on the supported catalysts

“…Hypothetical monomer-trimer and dimer-trimer diffusionless irreversible reactions on homogeneous surfaces between reactants of given pressures have been studied in [13,14,15] and [13,14,16,17], respectively, by employing a Monte Carlo simulations technique.…”

Adsorption–desorption Processes and Related Quantum Spin Models

“…They also contain some features which resemble the Dickman-Burschka 14 and Bretag-Davis-Kerr-Hurst generalizations of the random monomer problem, 15 extensions of the monomer filling problem with nearest-neighbor cooperative effects, 16,17 and other generalizations of simpli fied forms of catalysis. 18 Of course, there are potentially more processes which may be included if one is to have a realistic model of surface catalysis. However, we argue that restricting ourselves to simple stochastic rules is useful since it allows complete analytic treatments in some cases (as we shall see below), extensive numerical simulations and provides a starting point for generalizations such as addition of explicit diffusional relaxation mechanisms.…”
