Figures

FIG. 8. (A) The formation of CH, in the reaction of surface carbon with H, pulses on Rh,‘SiO, at different temperatures. The carbon was produced by injecting one pulse t I ml) of H, c CO, mixture (mole ratio 4: It onto the sample at 523 K. The sample was flushed with He before H, introduction. One H, pulse contained 41.6 Fmole H,. (B) The maximum amount of surface carbon transformed into CH, in the reaction with H, at different temperatures.

Frequently asked questions

Q1. What are the contributions mentioned in the paper "Methanation of co, on supported rhodium catalyst" ?

The synthesis of methane from CO, and H, was investigated on supported Rh catalysts. Evidence is presented to show that the surface formate is located not on the Rh, but rather on the support. The possible reasons for the different methanation rates of CO, and CO are discussed.
