Synthesis of monocarboxylic acids via direct CO2 conversion over Ni–Zn alloy catalyst |
| 초록 |
The direct conversion of CO2 to high value-added chemicals, such as acetic and propanoic acids (AA and PA, respectively), has not been explored to date. Herein, a Ni–Zn alloy/Zn-rich NixZnyO catalyst that directly converted CO2 to AA and PA with an overall selectivity of 77.1% at a CO2 conversion of 13.4% at 325 °C. The surface restructuring of the ZnO and NiO phases during calcination and subsequent reduction led to the formation of a Ni–Zn alloy on the Zn-rich NixZnyO phase. Surface-adsorbed (*CHx)n species were formed via the reverse water-gas shift reaction and subsequent CO hydrogenation. Afterward, monocarboxylic acids were produced via the direct insertion of CO2 into the (*CHx)n species and subsequent hydrogenation. The synthesis of monocarboxylic acid was highly stable up to 216 h on-stream over the Ni–Zn alloy catalyst, and the catalyst maintained its phase structure and morphology during long-term CO2 hydrogenation. |
