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

Synthesis of nanostructured powders and thin films of iron sulfide from molecular precursors

“…25,26 Nanoscale iron sulde has been synthesized with various morphologies by the decomposition of several single source precursors such as iron alkyl dithiocarbamates, 27 …”

HMTA-assisted One-pot Synthesis of Greigite Nano-platelet and Its Magnetic Properties

“…To simplify the experimental protocol, a single iron precursor is often preferred. However, a single iron source, whether Fe 2+ or Fe 3+ , often produces multiple iron sulfide phases [32,33] . If choosing Fe 3+ , a gentle reductant such as formic acid [24] or ascorbic acid [16] is necessary to be introduced to yield Fe 2+ ; while if using Fe 2+ , weak inorganic or organic oxidants like elemental sulfur [21,22,34,35] , polysulfide anions [35,36] , an appropriate amount of oxygen [14,35] , cysteine (possibly in the form of cystine) [4,17,20,35] and other organic species [19] are needed to produce Fe 3+ .…”

Synthesis of iron chalcogenides from single source precursors

“…XRD pattern matched with cubic phase Fe 3 S 4 . SEM images showed that both combinations of solvents produced Fe 3 S 4 nanoparticles …”

“…SEM images showed hexagonal shaped interconnected plate‐like structures. When solutions of oleic acid/OLA/ODE were used, XRD pattern indicated that samples were amorphous in nature and SEM image displayed nanoribbon morphology …”
