Sažetak
Industrial catalytic processes for converting greenhouse gas CO2 into valuable products have been actively explored in recent years. [1] Catalysts such as Cu/ZnO/Al2O3 are commonly used in this process. However, their selectivity towards methanol production is low. Therefore, there is a constant search for new and more efficient catalysts, with metal-organic frameworks (MOFs) showing enormous potential due to the high tunability of their physicochemical properties through structural changes. Ball milling has recently been used for the stoichiometrically controlled formation of bimetallic MM’-MOF-74 [2] and amorphization of MOF-74 materials. [3] To find out how the introduction of defects and the collapse of the porous structure of MOF by amorphization affects its activity and selectivity towards methanol, we studied the catalytic performance of crystalline and amorphous ZnCu-MOF-74 material. We compared it with monometallic Cu-MOF-74 and industrial Cu/ZnO/Al2O3 catalysts. Bimetallic MOF-74 was found to have better catalytic performance than monometallic one, while both the catalytic activity and selectivity of the bimetallic catalyst were improved by mechanochemical amorphization.[4] [1] A.
