Present study describes the fabrication of CuNPs (copper nanoparticles) by chemical reduction method and L-AA (L-ascorbic acid) use as a reducing as well as capping agent. Size of CuNPs was depending on the various concentration of L-AA. The synthesized CuNPs have resistance to oxidation by atmospheric oxygen for two months. The copper nanoparticles were studied by spectrophotometric techniques. The average sizes of copper nanoparticles were found to be 28, 16, 12 nm at increasing concentrations of L-ascorbic acid respectively. Interestingly, it was observed that, the activity depends on the size of particles. The catalysis by colloidal copper nanomaterials was studied kinetically with the oxidation of L-threonine (Thr) by peroxodi sulfate (PDS) at neutral pH. The copper nanoparticles are expected to be play important role in the field of catalysis and reduce water pollution.
