Abstract
Pyrite (FeS2) nanoparticles were produced by one-pot solvothermal synthesis, carried out at room pressure and mild temperature (≈180 °C). With this approach the sulfide anion is cogenerated during the synthesis. This method allows one to reduce the environmental impact, because the solvent, Fe and S are the only reactants involved in the process. A thorough characterization of the synthesis products was performed by SEM micromorphology, XRD, Diffuse Reflectance Spectroscopy (DRS) and XAS spectroscopy (both in the XANES and EXAFS regions).
