Catalytic Reaction between Methane and Nitrogen Dioxide. In the article "Demonstrating Heterogeneous Gas-Phase Catalysis with the Gas Reaction Catalyst Tube", the authors describe a heterogeneous palladium catalyst suitable for demonstrating continuous-flow, closed-system gas-phase reactions in the classroom or teaching laboratory. The gas reaction catalyst tube can be used to demonstrate a wide variety of gas-phase reactions, including several processes that occur in an automotive catalytic converter. In the reaction sequence shown, the red-brown color of the reactants can be seen to disappear while a fog of water forms in the product syringe. An automotive catalytic converter is shown in the background. Photographs by Jiro Fujita of Creighton University.
