In this work, dual active-site Ti-incorporated metal-organic frameworks (MIL-125 and NH2-MIL-125) were synthesized by a simple solvothermal process applied to prepare cyclohexanone oxime from cyclohexylamine oxidation. A low-temperature thermal calcination strategy was used for the modulation of surface properties while maintaining crystal structure morphology. The results demonstrated that novel bifunctional NH2-MIL-125@250 °C obtained possessed large area with both oxygen vacancies hydroxyl-active sites, promoting adsorption activation molecules, respectively. Under optimum conditions, conversion 44.3%, selectivity 83.0%. By comparison, stability MIL-125 NH2-MIL-125 investigated separately in cyclic tests, catalytic have been shown be more stable than those MIL-125. Combined density functional theory, it further displayed higher ability toward had ligand structure. Finally, plausible reaction pathway selective oxidation proposed. This work can give new insights into designing catalysts efficient transformation organic primary amines corresponding oximes.
