Abstract
- The aim of this work was to study the influence of copper content and particle morphology on the performance of Cu/FeO<subscript>x</subscript> catalysts in the gas-phase conversion of CO<subscript>2</subscript> with hydrogen. All four investigated catalysts with a copper content between 0 and 5 wt% were found highly efficient, with CO<subscript>2</subscript> conversion reaching 36.8%, and their selectivity towards C<subscript>1</subscript> versus C<subscript>2</subscript>-C<subscript>4</subscript>, C<subscript>2</subscript>-C<subscript>4</subscript>=, and C<subscript>5+</subscript> products was dependent on catalyst composition, morphology, and temperature. The observed range of products is different from those observed for catalysts with similar composition but synthesized using other precursors and chemistries, which yield different morphologies. The findings presented in this paper indicate potential new ways of tuning the morphology and composition of iron-oxide-based particles, ultimately yielding catalyst compositions and morphologies with variable catalytic performances.
