New chemical physics research from University of Bayreuth discussed
March 24th, 2009
According to a study from Bayreuth, Germany, "Rate measurements of the reaction CO+O -> CO2 on palladium(111) single crystal surfaces have been performed by means of mass spectroscopy under ultrahigh vacuum conditions. The total flux Phi of the impinging reactants CO and O-2 was held constant at 1 ML s(-1), whereas its CO fraction Y was varied between 0 (pure O-2) and 1 (pure CO)."
"The measurements have been performed for surface temperatures between 370 and 510 K and with a wide range of sampling times, evaluating the system parameter range for bistable behavior. Long-time measurements lasting several days proved the bistable behavior to result from two stable states...
