Sažetak
Carbon capture and storage technologies can significantly reduce our need for fossil fuels. Hydrogenation of CO2 to methanol over a mixed- metal Cu/ZnO/Al2O3 catalyst is a promising industrial process that can efficiently use CO2. [1] However, to further increase the selectivity of the process, new catalytic materials are being investigated. We wanted to determine whether the high porosity and accessibility of metal nodes in ZnCu-MOF-74 make this MOF suitable for this purpose. The catalysts were prepared by ball milling, which allows stoichiometrically controlled preparation of bimetallic ZnCu-MOF-74 materials.[2] The catalytic performance of the prepared ZnCu-MOF-74, monometallic Cu-MOF-74, and industrial Cu/ZnO/Al2O3 catalyst were evaluated. In addition, to assess whether the collapse of the porous structure of MOF-74 via mechanochemical amorphization may contribute to catalytic activity and selectivity, amorphized ZnCu-MOF-74 was also examined. Bimetallic MOF-74 was found to have better catalytic properties than monometallic one, while mechanochemical amorphization strongly affects both the catalytic activity and the selectivity of the bimetallic MOF-74 catalyst.[3]
