要旨

The irreversible adsorption of methanol on Pt/Ru catalysts is studied by simulation of the adsorption process on square and hexagonal lattice. It is assumed that three adjacent Pt sites are needed. The maximum degree of coverage is determined as a function of the Ru surface content. A simple first order adsorption kinetic equation, taking the maximum degrees of coverage into account, fits the simulation results well. It is shown that catalysts containing 10 to 30% Ru should have the best catalytic properties at low temperatures.
