This work investigates the effects of potassium addition on light olefin production from CO2 hydrogenation over the Al2O3-supported Fe–Co bimetallic catalysts. The addition of small amount of K on the Fe–Co catalyst significantly enhanced C2–C4 olefin formation. The C2–C4 olefins predominated among C2+ hydrocarbons at K/Fe atomic ratio of 1. Temperature-programmed desorption experiments demonstrated...
Nano-structured Pd catalysts with enhanced CH 3 OH synthesis activities for CO 2 hydrogenation were prepared by integrating two different effects, i.e., incorporation of uniform mesoporous support such as MCM-41 and SBA-15 leading to small Pd nanoparticles inside nano-sized pore channels, and promotion by alkali/alkaline earth metal additives. Pd supported on these mesoporous silica...
