| 抄録: | The effects of starting material and catalyst on the morphology of produced Si have been investigated for the direct electrolytic reduction of porous SiO₂ pellets in molten CaCl₂ at 1123 K. The Si nanowires (SiNWs) were produced using amorphous SiO₂ pellets with a tetrapod-like microstructure as the starting material, whereas plate-like Si was obtained from pellets made of spherical fumed SiO₂. The SiNWs showed irregular branching and a wide distribution of diameters as the electrolysis proceeded. On the other hand, elongated SiNWs were formed during the electrolysis of pellets comprised of Au nanoparticles (AuNPs) and tetrapod-like microstructured SiO₂ powder. This suggests that AuNPs work as catalysts for longitudinal nanowire growth in the present electrolytic process. |
