An Efficient Simple Hydrothermal Method to Synthesis FeS₂ Microspheres and their Optical Property

Abstract:

Pyrite (FeS₂) is an important semiconductor material which shows various excellent optical and electrical properties and extensive applied prospect as a new-type, photoelectrical functional materials. In this study, a low cost and efficient simple hydrothermal two-step synthetic method was given to obtain FeS₂ microspheres with 2-3 μm in diameter. The obtained products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and ultraviolet and visible spectrophotometer (UV-Vis). XRD showed that the synthetic sample consisted of two crystal structures of FeS₂, pyrite and marcasite. SEM observation indicated that FeS₂ microspheres were well crystallized and had good uniformity. UV-Vis spectrum had a strong optical absorption in the region of 200-400 nm wave length. The reaction temperature had an impact on the size of FeS₂ microspheres. A possible mechanism for the size of the FeS₂ microspheres generated at high temperature is smaller than that at low temperature is discussed.
