production over a model catalyst at 100 °C (both sides of the Ru(0001) sample covered with a film with 0.22 ML Au deposited, 13.4 mbar total pressure, round open symbols), background partial pressure increase over an inert substrate at 100 °C [both sides of the Ru(0001) sample covered with a film, 13.3 mbar total pressure, round filled symbols], and a Au foil at 150 °C (triangular symbols, total pressure of 20 mbars). All measurements were performed in a mixture.
