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).I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
