Solvothermal synthesis of Sb2S3 nanowires on a large scale

Sb2S3 nanowires with high aspect ratios have been successfully prepared on a large scale using SbCl3 and Na2S as starting materials in ethylene glycol at 200°C for 10 h. Field emission scanning electron microscopy images and transmission electron microscopy images show that the nanowires have diameters in the range of 20–100 nm and lengths up to 50 μm. Diffuse reflection spectrum indicates that the as-prepared Sb2S3 nanowires have obvious quantum size effects. The effects of reaction parameters on the growth of nanowires were discussed. A possible mechanism on the formation of the Sb2S3 nanowires was proposed.

The effect of agitation states on hydrothermal synthesis of Bi2S3 nanorods

The effect of agitation states on the synthesis of Bi2S3 was discussed via stirred-assisted, oscillated-assisted and static hydrothermal preparation methods. Results showed that agitation influences the crystallinity and size of Bi2S3 nanorods. It is of interest that Bi2S3 nanorods with a high degree of crystallinity are obtained via stirred-assisted hydrothermal method at the temperature as low as 95°C.

A rational complexing-reduction route to antimony nanotubes

Antimony nanotubes with inner diameters of 15–80 nm, wall thickness of 10–30 nm and lengths of up to several micrometers have been successfully prepared by a rational complexing-reduction route using zinc powder as reductant at low temperature (80–140 °C).

Seed-mediated growth approach to shape-controlled synthesis of Cu2O particles.

With glucose as reducing agent, Cu2O particles with different size and morphology were synthesized selectively by a seed-mediated growth approach. The major advantage of this process is that Cu(II) cannot be reduced to Cu metal. The size of the Cu2O particles can be controlled by changing the Cu(II) concentration in colloid solution. Square-shaped Cu2O particles (20-700 nm in diameter) were obtained in the presence of PEG 400, and polygonal-shaped Cu2O particles (approximately 1000 nm) were observed upon using triblock copolymer as modifier, while sphere-shaped Cu2O particles with a diameter of 400-700 nm were obtained in the absence of a modifier.
