O ct 1 99 7 Kinetic description of diffusion - limited reactions in random catalytic media
نویسندگان
چکیده
We study the kinetics of bimolecular, catalytically-activated reactions (CARs) in d-dimensions. The elementary reaction act between reactants takes place only when these meet in the vicinity of a catalytic site; such sites are assumed to be immobile and randomly distributed in space. For CARs we develop a kinetic formalism, based on Collins-Kimball-type ideas; within this formalism we obtain explicit expressions for the effective reaction rates and for the decay of the reactants' concentrations.

We study the effect of anisotropic diffusion on the one-dimensional annihilation reaction kA→inert with partial reaction probabilities when hard-core particles meet in groups of k nearest neighbors. Based on scaling arguments, mean field approaches and random walk considerations we argue that the spatial anisotropy introduces no appreciable changes as compared to the isotropic case. Our conject...
متن کاملKinetic study of ethanol and methanol electro-oxidation on Pd-vulcan XC-72R/Cu electrocatalyst in alkaline media
Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...
متن کاملO ct 1 99 3 Exact Results for Diffusion - Limited Reactions with Synchronous Dynamics
A new method is introduced allowing to solve exactly the reactions A+A→inert and A+A→A on the 1D lattice with synchronous diffusional dynamics (simultaneous hopping of all particles). Exact connections are found relating densities and certain correlation properties of these two reactions at all times. Asymptotic behavior at large times as well as scaling form describing the regime of low initia...

The diffusion coefficient of single particles in the presence of Ehrlich-Schwoebel barriers (ESB)is considered. An exact expression is given for the diffusion coefficient on linear chains with random arrangements of ESB. The results are extended to surfaces having ESB with uniform extension in one or both directions. All results are verified by Monte Carlo simulations.
متن کاملFABRICATION AND ELECTROCATALYTIC APPLICATION OF NI-MODIFIED ELECTRODE TOWARD DETECTION OF PARACETAMOL
In the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. The methods of cyclic voltammetry (CV), chronoamperometry (CA), and impedance spectroscopy (EIS) were used to determine kinetic parameters such as transfer coefficient (α), the catalytic reaction rate constants (k), and the diffusion coeffici...
