Catalytic hydrogenation of CO2 on rhodium surfaces: field emission techniques approach

An accurate characterization of the rhodium specimen was obtained via FIM experiments. Reaction behaviors between H2 and CO2 were observed in FEM mode at 700 K. At this temperature, CO desorption occurs and prevents CO+H2 reaction. The surface is mainly covered by oxygen, and the reaction with hydrogen occurs. Eventually, we can identify the reaction as the Reverse Water Gas Shift.
