CATALYTIC PROPERTIES OF NON-STOICHIOMETRIC URANIUM--THORIUM MIXED OXIDES IN CARBON MONOXIDE OXIDATION.

摘要: Abstract Non-stoichiometric uranium-thorium mixed oxides, of general formula UxTh1 − xO2 + y, have an important catalytic activity in carbon monoxide oxidation between 250 and 350 °C. Kinetic study the reaction is consistent with a mechanism based on oxido-reduction catalysts surface. A detailed pattern proposed discussed, where oxygen interstitial atoms play essential role.
