Abstract
|
Extracted microcrystalline cellulose from Carthamus tinctorius plant was oxidized by sodium metaperiodate and a
novel molybdenum schiff base complex was supported on this natural cellulose (MoSMC@MC). Then, micro
biopolymer silver/ immobilized molybenum complex on natural cellulose (Ag/MoSMC@MC) was synthesized at
the presence of Sesbania sesba plant and charaterized by SEM, FT-IR, TGA, and EDAX. The catalytic efficiency of
Ag/MoSMC@MC was exploited as a heterogenous bio-catalyst in the selective oxidation of alcohols. The reactions
were conducted using catalytic amounts of Ag/MoSMC@MC and t-BuOOH under solvent free conidtion to
obtain desired aldehydes and ketones in high yields and excellent selectivity. Long-term stability and reproducibility
in consecutive runs were feature of this microcomposite. At second part of this work, a novel
strategy was reported to obtain green nanocomposites. Herein, addition of silver nitrate to plant solution led to
the decomposition of the organic to inorganic polymer. As results, MoO3/Ag nanocomposite was prepared and
its characteristics were investigated using TEM, and XRD to confirm the shape and structure.
