Abstract
|
Extracted cellulose fibers from Quinoa wastes were successfully incorporated with
multi-walled carbon nanotubes/ZnO (MWCNTs/ZnO). Manganese complex was
supported on natural cellulose and reacted with MWCNT/Zn bio-nanocomposite to
have MWCNT/ZnO/Mn complex@oxidized cellulose. This novel bio-nanocomposite
was characterized by SEM, TEM, FT-IR, TGA, and EDS. The catalytic activity
of this composite was considered on the oxidation of alcohols. High conversion and
selectivities of desired aldehyde and ketone products were obtained applying H2O2
and under solvent-free conditions. This heterogeneous catalyst was easily recycled
and reused eight times without any significant catalytic activities and stabilities.
