摘要：

Nanocrystalline pyrite cobalt disulfide has been successfully prepared using the solvent-thermal method by the reaction of anhydrous CoCl2 with Na2S3 at 180 degrees C, which is similar to the well known hydrothermal process, except that toluene is substituted for water. The sulfur-to-metal ratio of the as-prepared product is 1.99:1, which is determined by chemical analysis. X-ray diffraction analysis indicates that the product is a single phase of pyrite cobalt disulfide. No Co-O vibrations are found in the IR spectra. Transmission electron microscopy shows that the average particle size is about 22 nm. (C) 1998 Elsevier Science S.A. All rights reserved.
