Synthesis, characterization of bio-derived ZnO nanoparticles and its catalytic activity

Synthesis of ZnO nanoparticles using Carica papaya leaf extract and its utility as nanocatalyst for preparation of oximes derivatives are reported here. Bio-derived ZnO nanoparticles were characterized by XRD, XPS, FT-IR, SEM, BET and TEM techniques. The substituted oximes were synthesized using ZnO nanocatalyst under microwave irradiation (MI) in solvent free condition with excellent yield (80 +/- 1.0-96 +/- 1.8%). The catalyst can be efficiently recycled up to 5th run. (C) 2015 Elsevier B.V. All rights reserved.
