Graphical Abstract
  • . Consequently, the electrocatalysts accelerate the reaction kinetics, improving the electrochemical performance of Na–S batteries. Different compounds were shown to have this property such as cobalt nanoparticles [34][45][46], iron nanoclusters [47] and iron disulfide [48], gold nanodots [49], nickel sulfide
  • . [48] also reported a promising cathode with iron in the form of iron disulfide nanoparticles as shown in Figure 6C. In order to explain the electrocatalytic behavior of FeS2, a two-step mechanism is proposed. Firstly, polysulfides are adsorbed on the surface of FeS2 NPs by strong chemical bonds and

Beilstein J. Nanotechnol. 2014, 5, 855–864, doi:10.3762/bjnano.5.97

Graphical Abstract
  • , dissolution of pyrite in water promotes the recycling of Fe2+ into Fe3+ and vice versa, triggering Fenton production of HO•, the primary species responsible for oxidative degradation of the pollutant. Our results with the synthetic pyrite nanoparticles demonstrate that H2O2 is indeed generated by iron
  • disulfide, in the absence of trace compounds founds in natural pyrite. Our kinetics analysis showed that the pyrite nanoparticles enabled a ca. 8 times greater efficiency of pollutant removal than did the microparticles. The use of synthetic pyrite nanoparticles avoids the dangers of heavy metal release
