Fe7S8 nanorods and nanosheets

Diverse-shaped iron sulfide nanostructures synthesized from a single source precursor approach

“…16 Kong et al obtained Fe 7 S 8 with highly interconnected structures of nanorods and nanoplates by a high-temperature approach in KI flux using sulfur and iron powders as the starting materials. 17 Recently, the single-source precursor (SSP) method attracts intense attention for nanomaterials synthesis because it permits a facile and reproducible production of colloid nanocrystals with the characteristics of single-crystallite, pure phase, and monodispersity. For examples, much better controlled-synthesis of iron sulfide nanocrystals has been achieved by utilizing singlesource precursors with both iron and sulfur elements integrated in the precursor in comparison with the liquid precipitation methods.…”

Shape-controlled synthesis of iron sulfide nanostructures via oriented attachment mechanism

“…In recent years, various methods have been proposed for the synthesis of iron sulfide nanostructures such as nanoparticles [14], nanowires [15], nanorods [16], nanosheets [17], nanoplates [18], and other complex morphologies [19] using vapor, solutionliquid-solid, vapor-liquid-solid [20,21], solvothermal [22,23], or template-directed [24] techniques. These methods generally use some form of the organic-phase synthesis technique to enhance the stability of the resulting nanostructure and to ensure a high monodispersity.…”

“Soft” Alkali Bromide and Iodide Fluxes for Crystal Growth

“…For applications in photocatalysis, silver-loaded sodium titanates were prepared by traditional solid-state and flux methods, and while several ABI fluxes were evaluated including NaBr and NaI, it was determined that the Ag/Na 2 Ti 6 O 13 prepared from a NaCl flux resulted in the highest CO formation rate and the highest selectivity to CO (Zhu et al, 2019). Kong et al determined that Fe 7 S 8 nanorods and nanosheets could be prepared from a KI flux and that the morphology of the nanostructures was dependent upon the reaction temperature, where nanorod formation was favored at 750 • C and nanosheets at 850 • C (Kong et al, 2005).…”
