Synthesis of nano-ferrite-Pd catalyst
Amine-functionalized nano-Fe (1 gm) was dispersed in water
and sodium palladium chloride solution in water was added
to the mixture to get 10 wt% of Pd. Hydrazine monohydrate
solution in water was added dropwise to bring the pH of this
mixture to 9, followed by addition of 0.1 gm of NaBH . The
reaction mixture was then stirred for 24 h at room temperature.
The product was allowed to settle, washed several times with

periodically determined by GC analysis. After completion of the
reaction, stirring was stopped. Within 30–45 s, the reaction mixture
turned clear and catalyst was deposited on the magnetic bar, which
was easily removed from the reaction mixture using an external
magnet. The crude product obtained was further purified by
column chromatography. All products are known in the literature
and were identified by comparison of their H and CNMR with
literature data and comparing their GC-MS spectra with standard
Wiley mass spectral library.
