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.
