Room-temperature synthesis of a bimetallic zeolitic imidazolate framework: An efficient catalyst for CO2 conversion at room temperature |
| 초록 |
A novel energy-efficient bimetallic heterogeneous catalyst system consisting of Zn and Co as active centers was synthesized at room temperature using low-boiling solvents. The newly synthesized material possesses RHO topology, similar to that of the parent monometallic zeolitic imidazolate frameworks (ZIFs), and the similar ionic radii of Zn2+ and Co2+ allow uniform distribution throughout the framework, as was confirmed through various physicochemical analytical techniques. The structural peculiarities of the newly synthesized bimetallic ZIF (denoted as ZnCo-ZIF) were exploited for CO2-epoxide cycloaddition reactions at room temperature and atmospheric pressure. The synergistic effects of multiple metal centers that cooperatively activate the epoxides led to superior catalytic activity compared to those of the corresponding monometallic ZIFs. In addition, a mechanism for the solvent-free CO2-epoxide cycloaddition reaction catalyzed by the bimetallic ZIF was proposed. |
