Synthesis of FeS2 Nanowires and Effect of Sulfidation Parameters on the Formation

Abstract

Abstract: FeS2 nanowires array was prepared by the combination of anodic alumina menbrane technique and sulfidation procedure. Scanning electron microscope (SEM) observation shows the bundles of oriented nanowires with very high aspect ratio before and after sulfidation. The X-ray diffraction (XRD) patterns reveal that the nanowires crystallize well with the cubic pyrite phase at higher temperatures, and sulfidation time has a little influence on the grain size during crystallization. X-ray photoelectron spectroscope (XPS) spectra show that a sulphur surface component is found additionally to the known pyrite signals.

Key words: anodic oxidation, electrodeposition, thermal sulfidation, FeS₂ nanowires
