Sonochemical method for preparation of bismuth sulfide nanorods

Different complexing agents including ethylenediaminetetraacetic acid, triethanolamine and sodium tartrate are used to obtain bismuth sulfide nanorods with different diameters and lengths. It was found that bismuth sulfide nanorods are successfully prepared by a sonochemical method from an aqueous solution of bismuth nitrate and sodium thiosulfate in the presence of complexing agents.
