“…[61] A mixture of decanethiol and oleic acid was used, and the morphology of the wires was found to be strongly dependent on the precursor ratio. Similarly, the morphology of Bi 2 S 3 [62] and Sb 2 S 3 [63] nanowires and nanotubes was also dependent on the precursor ratio, as reported by our group and by Son and coworkers. [64] Bi 2 S 3 nanowires were formed via a heterogenous nanocrystal route, [65] by reacting a bismuth citrate slurry in oleylamine with a sulfur solution in oleylamine [62] (Fig.…”

“…X-ray diffraction methods are also very difficult to interpret, due to the extreme difference of coherence lengths along different crystallographic axes, leading to the overlap of extremely broad and sharp features. [63,66] In addition, the peaks are expected to show some measurable shifts with respect to the bulk structures, as the nanowires experience a strongly anisotropic pressure due to their surface curvature.…”

“…Sb 2 S 3 nanowires and nanoplatelets could be formed with a thickness of $1.7 nm, by reacting antimony oleate with sulfur dissolved in oleylamine. [63] Similarly, nanotubes formed by the rolling up of a 1.7 nm-thick ribbon could be formed by reacting SbCl 3 with sulfur in oleylamine. [64] In this case, different from Bi 2 S 3 , the nanowires were single crystalline.…”

Ultrathin Nanowires—A Materials Chemistry Perspective

2009

View full text Add to dashboard Cite

The recent years have seen an explosive interest in one‐dimensional nanostructures1, as testified by the number of citations this field has accrued; as customary, its blossoming was enabled by chemical breakthroughs that allowed the reproducible and affordable synthesis of such structures.2, 3 The limitations of those syntheses was in the diameter of the nanowires that it could produce (hardly < 10 nm), and in the use of expensive and low‐yield techniques, such as chemical vapor deposition (CVD). This paper attempts to summarize the very recent chemical breakthroughs that have allowed the production of ultrathin nanowires, often in solution, and often in gram‐scale quantities. By no means is this a comprehensive coverage of the field, which can in part be found in other excellent reviews1, 2, 4–6 but a selection of those contributions that we feel would most help put this emerging field in perspective. We will review the various synthetic strategies, their pros and cons, and we will give our best guesses as to the future directions of the field and what we can expect from it.

“…Increasing interest in ultrathin nanomaterials is due to their attractive properties and various potential applications [6][7][8][9] . In particular, ultrathin metal sulphide nanocrystals have drawn tremendous attention owing to their unique properties arising from their exceptionally small dimensions and the resultant quantum size effects [10][11][12][13][14][15][16] . Importantly, the easy preparation and processability of these nanostructures makes them promising building blocks for a wide range of applications.…”

A general method for the large-scale synthesis of uniform ultrathin metal sulphide nanocrystals

et al. 2012

Ultrathin metal sulphide nanomaterials exhibit many unique properties, and are thus attractive materials for numerous applications. However, the high-yield, large-scale synthesis of well-defined ultrathin metal sulphide nanostructures by a general and facile wet-chemical method is yet to be realized. Here we report a universal soft colloidal templating strategy for the synthesis of high-quality ultrathin metal sulphide nanocrystals, that is 3.2 nm-thick hexagonal CuS nanosheets, 1.8 nm-diameter hexagonal ZnS nanowires, 1.2 nm-diameter orthorhombic Bi 2 S 3 nanowires and 1.8 nm-diameter orthorhombic Sb 2 S 3 nanowires. As a proof of concept, the ultrathin CuS nanosheets are used to fabricate an electrode for a lithium-ion battery, which exhibits a large capacity and good cycling stability, even after 360 cycles. Furthermore, high-yield, gram-scale production of these ultrathin metal sulphide nanomaterials has been achieved (B100%, without size-sorting process). Our method could be broadly applicable for the high-yield production of novel ultrathin nanostructures with great promise for various applications.

Pulsed Vapor‐Liquid‐Solid Growth of Antimony Selenide and Antimony Sulfide Nanowires

et al. 2009

View full text Add to dashboard Cite

Antimony sulfide and antimony selenide nanowires are prepared in an original pulsed vapor‐liquid‐solid growth mode. The molecular precursors are not mixed together in the gas phase; therefore the chemical reaction forming the solid only occurs in the gold catalyst. The material is stoichiometric and highly crystalline. Wires consisting of Sb2S3 and Sb2Se3 segments can be obtained with the same process.
