Abstract: Antimony dendrites have been successfully synthesized by a microwave-assisted method under ambient air from the solution containing antimony sodium tartrate. In the reaction, zinc powders were selected as a reductant for the fabrication. The as-prepared products were characterised by X-ray powder diffraction, transmission electron microscopy, and selected area electron diffraction. The dendrites were found to be composed of well-crystallized nanoflakes with size of 20–40 nm. [Copyright &y& Elsevier]

Abstract: A photochemical reaction route was developed to synthesize bismuth selenide (Bi2Se3) nanoparticles and nanorods. In an aqueous solution, bismuth nitrate (Bi(NO3)3) reacted with sodium selenosufate in the presence of reducing agent and complexing agent, and the dispersed Bi2Se3 nanoparticles were obtained with the average size of 35 nm. The nanorods were prepared via an alumina template route in the same solution. We carried out experiments to study the formation mechanism in the morphology control of the products and found that series of factors played an effective role including the irradiation time, pH value, the reducing agents and the species of complexing agents. The products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). [Copyright &y& Elsevier]
