Activation of Cu-, Ag-, Au/ZrO2 Catalysts for Dehydrogenation of Alcohols by Low-Temperature Oxygen and Hydrogen Plasma

We show that the effect of treatment of supported Mn+-ZrO2 catalysts is different in oxygen and hydrogen plasma. The activating effect of an oxygen plasma is connected with a decrease in the activation energy for dehydrogenation and with a change in the oxidation state of modifier ions. We obtain linear correlations of the catalytic characteristics with the reduction potential and radius of M in different oxidation states. © 2013 Springer Science+Business Media New York.
