Suppressing Methane Formation in CO2 Hydrogenation to Olefins over Ag-Promoted Na–Fe Catalyst
Methane formation remains a major selectivity loss in Fe-based CO2 hydrogenation to olefins, particularly at moderate-to-high CO2 conversion. Here, Ag was introduced into Na-promoted Fe catalysts to regulate the modified Fischer–Tropsch pathway. The effect strongly depended on the mode of Ag incorporation. Fe–Ag copr...
