Effect of Precursor Molar Ratio on the Yield of Cu Nanowires Synthesized using Aqueous Solution Method

Dedi Mardiansyah, Kuwat Triyana, Harsojo Harsojo


Synthesis yield of Cu nanowires using aqueous solution method has been controlled by varying the precursor molar ratios. The main materials in this experiment consisted of (1) a precursor of copper (II) nitrate trihydrate or Cu(NO3)2.3H2O, (2) a capping agent of ethylenediamine, and (3) a reducing agent of hydrazine. The synthesis process was carried out on the hot plate for 60 min with stirring rate of 60 rpm. For this purpose, the molar ratio of the precursor was varied from 0.012 to 0.2 M. Based on SEM images, we found that the ratio between nanowires and nanoparticles increased by decreasing precursor molar ratio. Furthermore, the Cu nanowires resulted from the synthesis were analyzed by XRD and SEAD, SEM-EDX, and UV-Vis spectroscopy to confirm crystalline properties, morphology and element distribution, and optical properties.
