Mechanistic Study of a Cs-Enhanced Pd/γ-Al2O3 Catalyst for the Reverse Water–Gas Shift Reaction

In the reverse water–gas shift (RWGS) reaction, Pd-based catalysts generally exhibit a high CO2 hydrogenation activity and a low CO selectivity due to the competitive methanation reaction. In this work, cesium (Cs), an alkali-metal promoter with strong basicity, is introduced to modify Pd/γ-Al2O3 catalysts for improv...
