Abstract:

Metal-organic frameworks (MOFs) have gained significant attention in recent years due to their unique structural and chemical properties, making them versatile for numerous applications such as adsorption, catalysis, and drug delivery. Our group has predominantly centered around MOFs based on Cu, Fe, Ga, Zn, and Zr post synthetically modified MOFs with Os, Au and Rh. These materials were employed in heterogeneous catalytic oxidation such as methane to methanol, cyclohexane to cyclohexanol, and CO2 conversion. Our research area is also focused in the enhancement of MOF stability, fast adsorption processes, and homogeneous & heterogeneous catalysis. In heterogeneous catalysis, our studies with Cu-based and Zr-functionalized MOFs demonstrated a progress in methane and cyclohexane oxidation. Furthermore, we assessed the stability of bimetallic Fe and Ga MOFs, priming them for environment with harsh oxidative conditions. Zr-based MOFs, dopped with Au and Rh nanoparticles, have been developed for the conversion of CO2. Lastly, a novel Zn-MOF, using quinolones as linkers, was applied for the removal of dye pollutants. In homogeneous catalysis, Os3(CO)12, bolstered by amines and heterocycles as co-catalysts, was used for the partial oxidation of both methane and ethane.
