Abstract
Surface-generated gas-phase hydroxyl radicals are formed when H2O and O-2 react over La2O3 at 900 degrees C. The addition of CH4 has a stron g, negative effect on the production of these radicals, which is attri buted to the competition between CH4 and H2O for an active form of oxy gen on the surface. At the temperature of these experiments, CO2 had n o effect on the formation of OH radicals.
