Structural requirements and reaction pathways in methane activation and chemical conversion catalyzed by rhodium
Kinetic and isotopic tracer methods led to a simple and unifying mechanistic proposal for reactions of CH4 with CO2 and H2O, for its decomposition on Rh clusters, and for water–gas shift reactions. Kinetic rates for forward reactions were measured by correcting net rates for approach to equilibrium and by eliminating transport artifacts. These rates were proportional to CH4 pressure (5–450 kPa)...
متن کاملThe Nanostructuring of Atomically Flat Ru(0001) upon Oxidation and Reduction
The O/Ru(0001) system is widely studied due to its rich phase variety of various stoichiometry and atomic arrangements, including the formation of a RuO2/Ru(0001) oxide layer. Apart from homogeneous ruthenium surfaces in certain oxidation states, also strongly heterogeneous surfaces can exist due to oxidation state's variation at the nanoscale. We report on a scanning tunneling microscopy (STM)...
متن کاملPredicting adsorption on metals: simple yet effective descriptors for surface catalysis.
We present a simple and efficient model for predicting the adsorption of molecules on metal surfaces. This heuristic model uses six descriptors for each metal (number of d-electrons, surface energy, first ionization potential and atomic radius, volume and mass) and three for each adsorptive (HOMO-LUMO energy gap, molecular volume and mass). Strikingly, despite its simplicity and low computation...
متن کاملElectronic process of Cu(Ag, V, Rh)(0 0 1) surface oxidation: atomic valence evolution and bonding kinetics
The electronic processes of Cu(Ag, V, Rh)(0 0 1) surface oxidation are comparatively analyzed based on the recent ‘chemical bond–valence band–potential barrier’ (BBB) correlation mechanism [C.Q. Sun, Prog. Mater. Sci. 48, 521–685 (2003)], which allows reaction formulae for all the observed phases with identification of individual atomic valence and the binding kinetics at the surfaces with the ...
متن کاملCO oxidation on ruthenium: The nature of the active catalytic surface
The oxidation of CO, i.e. CO + =2O2 ! CO2, over metal surfaces is one of the most studied catalytic reactions. The details of the reaction mechanism under ultrahigh vacuum (UHV) conditions have been well understood for some time [1]. Under reducing or mildly oxidizing conditions for Pt, Pd, and Rh, metals used in automotive catalytic converters, the reaction proceeds via the Langmuir–Hinshelwoo...
