Abstract:
Electrolysis of solid oxides in molten chlorides were well documented as a greener and more affordable preparation of silicon and/or germanium powders which are building blocks not only for traditional metallurgical industries and also for high-tech areas including solar cells, batteries, chips and etc. Deep and thorough insights into the reaction mechanisms and structural characteristics of the electrolytic samples are the prerequisites on optimizing the process and fully exploiting the functionalities of electrolytic samples. Herein, the existence of liquid process during electrolysis of solid SiO2 and GeO2 in molten chlorides was verified. The implications of the forenamed liquid process on the energy efficiency, chemical compositions and microstructures of the electrolytic products were also discussed. Reaction mechanisms on the controllable preparation of Si and/or Ge with different nanostructures including nanoparticle, one-dimensional nanostructure, porous nanostructure and hollow nanostructure were also highlighted.
