Abstract

Pulse chemisorption studies reveal that a subsequent reaction is part of the mechanism of the formation of synthesis gas from CH4 and CO2, known since 1928. In the first step CH4 is decomposed on a Rh/A12O3 catalyst into reactive surface carbon CS and H2; in the second step C8 reacts with CO2 to give CO, but it is still not clear whether this step is also catalyzed by Rh.
