Copper nanoparticles were prepared by hydrogen reduction by electrolysis of water. The formation, structure and morphology of products were characterized by X-ray diffraction analysis (XRD), Scanning Electron Microscope (SEM) and the specific surface area (BET) was determined by N2 physisorption Brunauer - Emmitt - Teller (BET) method. The results showed that copper particles are a simple phase and the size about 40-70 nm, the BET-surface area as 15.85 m2/g. The data showed that copper nanoparticles increased germination rate of maize at normal condition.

Keywords: Copper nanoparticles, reverting method.
