This paper presents the results of research on the fabrication of zero-valence Fe/Cu bimetallic nanomaterials by polyphenol agent extracted from Vietnamese green tea leaves. The influence of a number of factors on the fabrication process has been studied, showing that the zero-valence Fe/Cu bimetallic nanomaterials have the best quality when dispersed in a 4/1(v/v) ethanol/H2O solvent mixture; polyphenol concentration in green tea extract 12.5 g/L; Fe/Cu ratio is 5/1, pH = 3 - 4, temperature 25 - 28 oC. Fe/Cu bimetallic nanomaterials have stable activity for 35 days, d = 0.921 g/cm3, particle size 37 - 45 nm and contain hydroxyl groups on the surface.
