| 摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to nanotechnologies in field of chemistry. Method includes interaction of silicon compound of tetraethylorthosilicate with reducing agent - sodium borohydride in presence of ionic liquid, containing dialkyl imidazolium cation, in organic solvent medium and separation of silicon nanoparticles that are formed. As ionic liquid 1,3-dimethylimidazolium iodide can be used, diglyme being used as organic solvent. Interaction is carried out in inert gas atmosphere. Invention ensures obtaining nanocrystalline silicon in absence of silicon halogenides and metallic sodium in conditions of homogenous reaction.EFFECT: method is technological and easily reproducible.4 cl, 3 dwg, 1 ex |
