Hydrogenation of CO2 on Nanostructured Cu/FeOx Catalysts: The Effect of Morphology and Cu Load on Selectivity

The aim of this work was to study the influence copper content and particle morphology on performance Cu/FeOx catalysts in gas-phase conversion CO2 with hydrogen. All four investigated a between 0 5 wt% were found highly efficient, reaching 36.8%, their selectivity towards C1 versus C2-C4, C2-C4=, C5+ products dependent catalyst composition, morphology, temperature. observed range is different from those for similar composition but synthesized using other precursors chemistries, which yield morphologies. findings presented paper indicate potential new ways tuning iron-oxide-based particles, ultimately yielding compositions morphologies variable catalytic performances.
