Converting organosulfur compounds into nano-iron sulfide (nFeS) by solvothermal synthesis. a Garlic-derived and other natural organosulfur compounds. The number in red is the computational calculated value of bond dissociation energy (BDE) for the S-related bonds (in kcal mol−1). b The scanning electron microscope (SEM) image of nFeS with sheet-like hexagonal nanostructure. Scale bar: 1 µm. c XRD characterization of nFeS in the two phases of Fe1-xS and Fe3S4. d The transmission electron microscope (TEM) image (left image) of nFeS with high resolution characterization (right images) and single-crystal diffraction (inserted images). Left scale bars: 200 nm. Right scale bars: 2 nm. d1: d-spacing at 0.298 nm. d2: d-spacing at 0.15 nm. e Scheme of converting organosulfur compounds to nFeS with Fe3S4 and Fe1-xS. All experiments were performed in triplicate, and the representative images are shown
