Abstract
|
MoO3 nanoparticles were obtained using Sesbania sesban. Novel Schiff base ligand and its nanocomplex of copper
were synthesized under ultrasonic irradiation. First MoO3/Copper Schiff base complex nanocomposite (NMCS)
based on this natural plant was prepared and characterized by TEM, SEM, AFM, FT-IR, TGA, EDAX and elemental
analysis. Then atom-efficient and selective oxidation of alcohols using hydrogen peroxide catalyzed by
NMCS bio-nanocomposite under ultrasonic irradiation was reported. Structurally diverse set of alcohols was
transformed into desired aldehyde and ketone products with high conversion and excellent selectivity under
solvent free conditions. Products were isolated easily from green media, and the catalyst could be reused six
times without any appreciable decrease in catalytic activity and selectivity.
