Abstract
- Mineral nanocrystalline Cu3BiS3 and <F>Pb1−xBi2x/3S</F> (or Bi0.22Pb0.89S1.22) have been prepared at low synthetic temperature of 100–150 °C by convenient hydrothermal decomposition process. X-ray powder diffraction, transmission electron microscopy, X-ray photoelectron spectra, and element analysis were used to characterize and measure the samples. The as-prepared Cu3BiS3 sample consisted of whisker-like particles with an average size of <F>50×10</F> nm2 and the <F>Pb1−xBi2x/3S</F> sample displayed aggregative particles with size in the range of 30–50 nm. Preliminary results showed that the prepared precursors, reaction temperature and time played a role in the formation of the final products. A possible reaction mechanism was also discussed briefly.
