| Abstract: | The state of metals in Rh–Fe/SiO2 catalysts has been examined. Iron is shown to form clusters with rhodium, whose size and composition depend on the metal ratio in the catalyst. The structure of active sites affects the amount and adsorption heat of hydrogen and carbon monoxide and their interaction mechanism.
