Formation of Carbon Nanostructures in Electrolytic Production of Alkali Metals

摘要

Carbon-based solid phase containing open and closed multiwalled carbon nanotubes(up to 5% of the total carbon)was found in the waste from industrial production of metallic lithium by electrolysis of lithium chloride melt with graphite electrodes.The electrochemical method of preparation of carbon nanostructures [1,2] and,in particular,carbon nanotubes(CNTs)was developed and studied somewhat later than the electric arc method [3] and virtually simultaneously with that CVD method(chemical vapor deposition,i.e.,chemical decomposition of volatile carbon-containing substances in the presence of catalysts)and HIPCO.
