The FeS2 was synthesized using S powder, FeCl24H2O and PVP as main raw materials by solvothermal method. The FeS2 product was characterized by XRD, SEM, DRS and TG-DTA. The results show that FeS2 is the cube structure, particle size about 90 nm, band gap energy Eg=1.9 eV. Consequently, FeS2 nanoparticles show high visible-light photocatalytic activity for decomposition of methylene blue, which degradation rate of 10mg/L methylene blue solution can reach to 95% for 90 min under visible-light irradiation.
