Using a straightforward method, this study fabricated an eco-friendly low-cost magnetic nanocomposite consisting of magnetic carbon nanotube/MOF as a stabilizer. Pd nanoparticles (Pd NPs) were then decorated on the
designed magnetic carbon nanotube/MOF microspheres, and the resulting magnetic carbon nanotube/MOF/Pd
NPs nanocomposite were employed as heterogeneous catalysts in Aerobic oxidation of primary and secondary
alcohols. The attractiveness of this work is in the selective oxidation of several types of active and inactive
alcohol substrates. The most important feature of this catalyst is its successful recovery and simple separation
repeatedly without reducing its activity and selectivity. The active surface area of this Nanocatalyst is very large
due to its structural properties, and as a result, it provides more available catalytic sites, which increases its
activity. The identification techniques used to investigate the structural properties of this Nanocatalyst confirm
its successful synthesis and appropriate palladium loading into the catalyst sites. The oxidation of alcohols was
determined by Gas Chromatography (GC). The 100% selectivity, excellent turnover number (TON), high yield,
almost complete and fast conversion of alcohol to the desired aldehydes and ketones without more oxidation, and
easy and no-trouble isolation of product and catalyst are outstanding features of this catalytic system. The use of
picolinaldehyde lead to the high loading of Pd NPs, reducing the catalyst content needed for the reaction.
Regarding the high catalyst loading, using a small amount of catalyst is recommended for proceeding with the
reaction efficiently.
