Abstract


New copper nanoparticles (CuNPs) have been synthesized via chemical reduction method in the presence of rice straw as supports and seaweed as a stabilizer. Characterizations of the CuNPs were carried out using UV-visible spectroscopy (UV-vis), Fourier Transform Infrared (FT-IR), Field Emission Scanning Electron Microscopy (FESEM), and Energy Dispersive X-ray (EDX). The UV-vis adsorption spectra confirm the formation of CuNPs through the peaks of the surface plasmon resonance (SPR) bands around 500 to 600 nm. Morphological characterization showed the formation of a spherical structure of the CuNPs. Similarly, EDX spectra showed that the nanoparticles produced are copper based. The size of nanoparticles formed by this method was controlled easily by using different concentration of rice straw.
