Formation of Group 11 Bismuth Sulfide Nanoparticles Using Bismuth Dithioates under Mild Conditions

Abstract

The formation of mixed-metal sulfides with the general structure AgBiS and Cu BiS by a simple two-step process utilizing bismuth dithiocarboxylates as Bi and S precursors is described. A sonochemical reaction of Bi O with six different aryl dithioic acids: dithiobenzoic acid (BDT-H), 4-methoxydithiobenzoic acid (4-MBDT-H), 3-methyldithiobenzoic acid (3-MBDT-H), 2-mesitylenedithioic acid (2-MDT-H), 4-fluorodithiobenzoic acid (4-FBDT-H), and 2-thiophenedithioic acid (2-TDT-H) resulted in the corresponding complexes: [Bi(BDT) ] 1, [Bi(4-MBDT) ] 2, [{Bi(3-MBDT) } ⋅C H ] (3 ⋅C H ), [Bi(2-MDT) ] 4, [Bi(4-FBDT) ] 5 and [Bi(2-TDT) ] 6. Microwave irradiation of these bismuth(III)aryldithioate complexes with AgNO or CuCl under mild reaction conditions (140 °C) resulted in the respective mixed-metal sulfides. Attempt to synthesize AuBiS using similar reaction protocols were unsuccessful, resulting only in the formation of elemental Au , S and BiOCl.

Phase‐Controlled Synthesis of High‐Bi‐Ratio Ternary Sulfide Nanocrystals of Cu1.57Bi4.57S8 and Cu2.93Bi4.89S9

“…Generally, ternary Cu−Bi−S sulfides could be synthesized with reactive sintering method, solvothermal method, polyol route, chemical bath deposition method,, vacuum‐sealed solid state reaction, and colloidal hot‐injection method ,. The controllable synthesis of metal sulfide nanocrystals should be assistant by sorts of thio‐ligand precursors, which results in many efforts in developing new precursors for the semiconductor sulfide nanocrystal preparation . For example, Wang et al have reported a generalized strategy for the synthesis of seven ternary sulfides by using one‐pot method from single source of metal‐diethyl dithiocarbamate precursors .…”

Silver Bismuth Sulfoiodide Solar Cells: Tuning Optoelectronic Properties by Sulfide Modification for Enhanced Photovoltaic Performance

“…A small amount of hydroiodic acid (3 vol.%) was added to the precursor solution to improve the crystalline and morphological stability of the resulting materials. [21] Modification of the metal iodides with the sulfide dianion was achieved by introducing reactive bismuth(III) tris(4-methylbenzodithioate) (hereinafter, Bi(S 2 CAr) 3 ) [34] to the precursor solutions. This choice was motivated by the solubility of bismuth benzodithioates in various organic solvents and their ability to decompose to bismuth(III) sulfide at low temperature (100-150 °C) in air.…”

“…Senevirathna 218 did a double conversion-Bi 2 O 3 was converted to the sulfide using aryldithioic acid and then to Cu 3 BiS 3 using CuCl. This formed agglomerated particles 70-80 nm in size.…”
