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.
