Iron sulfide (FeS 2 and Fe 7 S 8 ) has been considered as one of the promising electrode materials in the field of solar cell and lithium ion battery owing to their unique properties. Herein a facile solvothermal method is reported for preparing iron sulfide/carbon nanotube (CNT) nanocomposites with desired structure and composition. FeS 2 nanoparticles can be successfully loaded on the surface of CNT, and the FeS 2 nanoparticles uniformly distribute along the CNT. With the assistance of polyvinylpyrrolidinone (PVP), flower‐like Fe 7 S 8 @CNT precursor and flower‐like Fe 7 S 8 precursor can be obtained, respectively. When the flower‐like precursors are annealed in the tube furnace with Ar atmosphere, the diameter of the samples decrease from micron level (≈1 µm) to submicron‐level (200–400 nm).
