Towards an oscillation mechanism for the NO-CO reaction on Rh〈110〉: NO dissociation kinetics and oxygen subsurface diffusion

Static secondary ion mass spectrometry (S-SIMS) Part 2: material science applications

“…Speci®cally, the structure of the detected ions suggested two adsorption states: a three-fold coordinated NO adsorption at low coverages and a two-fold NO adsorption at high coverages. The use of (TP) S-SIMS is also applicable to more complex systems, e.g., reactions of NO with C 2 H 4 co-adsorbed on Rh(111) and with CO on Rh(110) surfaces (van Hardeveld et al, 1996;1997a;Schmatloch et al, 1995). The preparation of atomic nitrogen layers on Rh(111) monolayers by adsorption of NO and selective removal of the atomic oxygen by reaction with H 2 , could be followed by monitoring the Rh 2 N , Rh 2 O and Rh 2 NO signals (van Hardeveld et al, 1997b;1997c).…”

Effect of experimentally observed hot atom adsorption mechanism on the phase diagram of monomer-dimer catalytic reaction on Pt(111): a Monte-Carlo simulation study

“…Experiments show that the production of CO 2 starts as soon as y CO departs from zero [9][10][11]. Inspired by the work of Ziff et al [7], different authors have studied variants of the ZGB model [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] .…”

Zooming in on the initial steps of catalytic NO reduction using metal clusters

“…Here, CO and HC are the reductants for NO, while N 2 , CO 2 , and H 2 O are formed as the final products. [11][12][13][14][15][16][17][18][19][20] Rh is considered to be the main element active in the catalytic chemical reduction of NO. Because of this unique ability, over 80% of the global Rh demand is for TWCs.…”
