Taking bismuthinite to bismuth sulfide nanorods in two easy steps†
Abstract
The transformation of mineral bismuthinite, to Bi2S3 nanoparticles, via a simple two-step process is described. The reaction of bismuthinite with two aryldithoic acids gave the complexes; [Bi(S2C(C6H4)-4-CH3)3] and [Bi(S2C(C6H4)-4-OCH3)3]. Mild solution decomposition (120 °C) of these bismuth aryldithioates produced crystalline Bi2S3 nanorods.
