Abstract
- A microwave-assisted hydrothermal synthesis produces ZnFe<subscript>2</subscript>O<subscript>4</subscript> containing Na residue as a precursor to a CO<subscript>2</subscript> hydrogenation catalyst that displays high CO<subscript>2</subscript> conversion and high selectivity to liquid hydrocarbon products in the gasoline and diesel range with high olefin-to-paraffin ratios. Compared to reference catalysts derived from Fe<subscript>2</subscript>O<subscript>3</subscript> and a ZnO-Fe<subscript>2</subscript>O<subscript>3</subscript> physical mixture, the ZnFe<subscript>2</subscript>O<subscript>4</subscript>-derived catalyst contains well-dispersed iron particles with Zn serving as a structural promoter. A profound effect of the residual Na as an electronic promoter is also observed, which improves the selectivity for C<subscript>5+</subscript> hydrocarbons and olefins. The ZnFe<subscript>2</subscript>O<subscript>4</subscript>-derived catalyst exhibits excellent performance in the CO<subscript>2</subscript> Fischer-Tropsch reaction as it forms the active Hägg iron carbide (χ-Fe<subscript>5</subscript>C<subscript>2</subscript>) phase readily through the in situ carburization of iron.
