“Scission–template–transportation” route to controllably synthesize CdIn2S4 nanorods

Abstract

By using a novel method denoted the ''Scission-template-transportation'' route, CdIn 2 S 4 nanorods with stoichiometric composition and high quality can be prepared in an ethylenediamine-ethanol mixed solvent at a relatively low temperature. Transmission electron microscopy images showed that the product from the 1 : 1 mixed solvent was rod-like with an average size of 25 6 700 nm. Ethylenediamine serves as the nucleophile for the formation of the inorganic [Cd 2 S 2 ] core by scission of the thione groups of cadmium bis(diethyldithiocarbanate) [Cd(DDTC) 2 ] 2 while ethanol acts as the transportation reagent for InCl 3 in the process. These factors are both conducive to the growth of CdIn 2 S 4 nanorods. The reaction proceeds through one-dimensional [CdS] n clusters, which act as intermediate templates for the subsequent growth of CdIn 2 S 4 nanorods. Through adjusting the ethylenediamine : ethanol ratio, the size of the CdIn 2 S 4 nanorods can be easily controlled. The products were also investigated by X-ray powder diffraction, X-ray photoelectron spectroscopy and ICP elemental analysis.

Solvothermal Synthesis of CdS Nanowires in a Mixed Solvent of Ethylenediamine and Dodecanethiol

“…This compound was precipitated initially via a reaction between cadmium salts and dodecanethiol. Nevertheless, under the solvothermal conditions, the reaction between Cd(SC 12 H 25 ) 2 and the sulfur source (NaS 2 CNEt 2 ) would occur immediately and generate some intermediates such as Cd(SC 12 H 25 )(NaS 2 CNEt 2 ) and Cd(S 2 CNEt 2 ) 2 4 TEM images of four samples, showing different growth stages of CdS nanocrystals.…”
