Rh/gamma-Al2O3 and Pt/gamma-Al2O3 catalysts supported on a metal foil surface have been studied in the carbon dioxide reforming of methane. The stability and activity of platinum and rhodium catalysts with different compositions have been determined. The kinetic function parameters have been found by solving the inverse problem. It has been shown that the 0.06% rhodium catalyst is the most active; its activity is more than two orders of magnitude higher than that of the nickel-chromium catalyst studied earlier.
