Abstract :

Concentration of CO2 in the atmosphere continues to rise due to various human activities. Catalytic conversion of CO2 into valuable chemicals has attracted attention of many researchers around the world as it provides an alternative route to deal with CO2 emission to atmosphere. In this study, Cu/ZnO catalyst is synthesized on multi-walled carbon nanotubes (CNTs) via incipient wetness impregnation method. The physicochemical properties of the catalysts have been analyzed using TEM, XRD, N2 adsorption, H2-TPR and XPS. The activity of the synthesized catalysts have been evaluated in a hydrogenation reaction of CO2 using a fixed-bed micro reactor at 503 K and 22.5 bar. BET analysis revealed that the specific surface area of the sample decreased after deposition of metals onto the treated CNTs support. Observation via TEM showed agglomeration of nanoparticles on the exterior surface of the treated CNTs. Results of XPS analyses indicated the presence of Cu2+ in the catalyst sample. Evaluation of the synthesized catalyst in CO2 hydrogenation reaction resulted in CO2 conversion of 23% with selectivity of 73.7%, 2.0%, 21.9% and 2.4% for methyl formate, ethanol, methanol, and methane, respectively.
