Synthesis of porous CuInS₂ crystals using a stirrer

Abstract

Porous CuInS2 crystals were grown from starting materials CuCl2·2H2O, InCl3·4H2O and thiorea with ethylene glycol solution, that were placed into a flask, heated, and refluxed for 1 hour. The diffraction peaks only from CuInS2 phase appear for all the samples. The morphology of CuInS2 crystal was porous, and the porous crystals exist in two kinds. One kind was flower‐like crystals which complexly lack the flakes, another one was sphere‐like crystals existed with a number of the poles. The specific surface area of the samples grown by stirring starting materials with In to Cu ratio of 4.3 for 30 minutes was found approximately to be 55 m2/g. (© 2013 WILEY‐VCH Verlag GmbH & Co.

Mechanochemical Synthesis and Characterization of CuInS2/ZnS Nanocrystals

“…This value is similar to those reported in references [39,40], in which also mechanochemical approach was used. In the case of high-temperature synthesis of CuInS 2 starting from compounds, yielding the S BET value of 30 m 2 /g was registered by Akaki et al [47]. The addition of ZnS into the system significantly increased the S BET value up to 86 m 2 /g, which is in accordance with the porous character of ZnS.…”
