FeS2 nanocrystals were synthesized by the reaction of Fe(NO3)3·9H2O with NH2CSNH2 in ethylene glycol via a solvothermal process using PVP as surfactant.The products were characterized by XRD and TEM.The results show that PVP plays a significant effect on the phase and morphology of the as-synthesized nanocrystal FeS2.
