Selective oxidation of active and inactive alcohol substrates and reduction of nitroarenes is a highly versatile
conversion that remains a challenge in controlling functionality and adjustments in metal−organic frameworks (MOFs). On the
other hand, it offers an attractive opportunity to expand their applications in designing the next generation of catalysts with improved
performance. Herein, a novel mixed MOF consisting of supported 2-hydroxybenzamide (mixed MOF-salinidol) has been fabricated
by post-synthetic modifications of mixed MOF. Subsequently, the prepared nanocomposites were modified to impart catalytic sites
using palladium chloride ions mixed with MOF-salinidol/Pd (II). After successfully designing and structurally characterizing
nanocomposites, we evaluated their activity in oxidizing primary and secondary alcohols using aerobic conditions with molecular
oxygen and an air atmosphere. In addition, the stability of (mixed MOF-salinidol/Pd (II)) catalysts under catalytic conditions was
also demonstrated by comparing the Fourier-transform infrared spectrum, scanning electron microscopy image, and ICP-OES
method before and after catalysis. Based on the results, the active surface area of the synthesized nanocatalyst is large, which
highlights its unique synergistic effect between post-synthetic modified MOF and Pd, and furthermore, the availability of catalytic
sites from Pd, as demonstrated by outstanding catalytic activity
