Abstract: A feasible one-pot synthesis method for the preparation of copper nanoparticles under ambient atmosphere is put forward. Copper oxide and D-isoascorbic acid were chosen as the copper precursor and mild reducing agent, respectively. Oleylamine and octylamine were selected as the capping agents. The effects of the amount and alkyl chain length of capping agent on the synthesis of copper nanoparticles were studied. Antioxidised copper nanoparticles were prepared successfully without the protection of inert atmosphere. The minimum average size of obtained copper nanoparticles was 149 ± 11 nm.

Keywords: nanoparticles; copper; one-step process.
