Herein, a new catalytic nanocomposite [Co(BDC-NH2)-Pd NPs] composed of a Co(BDC-NH2) MOF has
been developed. The catalyst was prepared by modifying the synthesized porous Co(BDC-NH2) MOF
with decorated Pd nanoparticles. This nanocatalyst was used as a heterogeneous catalyst in the
reductive degradation of organic dyes Rhodamine B and methyl orange with NaBH4. The kinetic and
thermodynamic parameters of the reactions were evaluated. The results showed that the low catalyst
content could successfully catalyze the dye reduction reaction quickly (1 min). The metal–organic
frameworks unique porous morphology of the Co(BDC-NH2) MOF appears to increase dye adsorption
and achieve effective dye reduction. Additionally, recyclability studies of the catalyst confirmed that it
could be recovered and reused for 10 consecutive reaction cycles with negligible Pd leaching and
reduction in catalytic activity.
