Template-directed Synthesis of Ag2S-Fe2O3 Heterostructures
Herein, we demonstrated the synthesis of nanocomposites containing silver sulfide and iron oxide materials by the sulfidation of silver-iron oxide nanotemplates with elemental sulfur as sulfur resource. In the presence of oleylamine, the sulfidation of silver-iron oxide heteromers retained similar nanostructures as templates, indicating an in-situ sulfidation of silver. TEM images, UV-Vis absorption spectra and XRD patterns of as-prepared Ag-Fe2O3 and Ag2S-Fe2O3 nanoparticles synthesized by sulfidation with elemental sulfur were shown in this paper. These investigations would help us to understand the sulfidation and growth process of nanomaterials and control their synthesis for a given application.
