The gravitational level effect has been recognized in the uniformity of PL characteristics of electrodeposited ZnO nanowire arrays. Amorphous Si thin film has been also electrodeposited in ionic liquid(TMHATFSI-0.1MSiCl4) as well as PC organic electrolyte. Based on these achievements, the electrodeposition of Si nanowire is now challenging. Amorphous SiO2 powder refined from diatomaceous earth (DE-SiO2, 5N in purity) are pressed into pellets, and the electrolytic reduction of them is investigated in molten CaCl2 at 1123 K. DE-SiO2 pellets are successfully reduced to Si at 1.00 and 1.20 V vs. Ca(2+)/Ca. Rod-like nanostructure is observed in SEM of reduced Si sample. Furthermore, the reduction rate of DE-SiO2 pellet is higher than that for fumed-SiO2 pellet. DE-SiO2 will be one of the most promising Si sources in the industrial-scale electrolytic reduction in both aspects of the reduction rate and the abundance of the resources., 共催: 日本学術会議, 著者人数: 29人, joint hosting: The Science Council of Japan, 資料番号: AA0064730029}, pages = {77--80}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {Non-equilibrium Electrochemical Processing of Nano-structured Energy Conversion & Storage Devices}, volume = {26}, year = {2010} }
