Kerman Researchers Produce “Nanocatalist” From Carthamus Tinctorius

Saturday, September 22, 2018 - 12:38

Researchers of Jiroft University in cooperation with Payam-e Noor University of Kerman have investigated an innovative synthesis of MoO3/Ag nanocomposite and catalytic application of immobilized molybdenum complex on cellulose extracting from Carthamus tinctorius.

Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products. Most of these materials have been imported into the country so their domestic production can save currency significantly.

Based on the research, 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.

The study was carried out by Atena Naeimi, faculty member of University of Jiroft, Sayed Zia Mohammadi and Asma Sedri, faculty members of Payame Noor University.

The result was released in the journal of Carbohydrate Polymers (Volume 199, 1 November 2018, Pages 236-243)
