Electrochemical investigation of uncapped AgBiS₂ (schapbachite) synthesized using in situ melts of xanthate precursors

Abstract

In this study, a facile and potentially scalable synthesis of AgBiS2 (schapbachite) using melts of metal xanthates is presented; AgBiS2 is both a significant mineral and a technologically important material.

Synthesis and characterization of zinc di(O-2,2-dimethylpentan-3-yl dithiocarbonates) bearing pyridine or tetramethylethylenediamine coligands and investigation of their thermal conversion mechanisms towards nanocrystalline zinc sulfide

“…Metal dithiocarbonates, also known as metal xanthates, belong to this class of materials and their use for the preparation of a wide range of metal sulfides, for instance, CdS, 24,25 ZnS, 26,27 NiS, 28 SnS, 29 PbS, 30 Ga 2 S 3 , 31 Bi 2 S 3 , 32 CuInS 2 , 33,34 CuSbS 2 , 35 and Cu 2 ZnSnS 4 36 is already reported. A further beneficial property of metal xanthates as precursors is that the conversion can take place via thermal treatment in solution, 37,38 solid state reactions in a matrix, 39,40 solvent-free melt reactions [41][42][43] or aerosol assisted chemical vapour deposition (AA-CVD) processes. 44,45 Additionally, by mixing different ratios of metal xanthates, doped metal sulfides with various transition metals can be resulted and several studies showed that such systems are very useful for controlling the optical, electrical and crystalline properties.…”

Direct solvent free synthesis of bare α-NiS, β-NiS and α-β-NiS composite as excellent electrocatalysts: Effect of self-capping on supercapacitance and overall water splitting activity

“…Nickel sulfides have been prepared by several routes and nanostructured materials of different properties have been obtained 16 . The use of single source molecular precursors has produced high quality nanomaterials of various types over the years [35][36][37] . However, the synthesis of phase pure nickel sulfide nanomaterials from single molecular precursors are limited, mixed-phase systems are normally generated.…”

“…electrochemical studies. Electrochemical investigation of the synthesized materials was carried out using Gamry Potentiostat by three-electrode system, according to the protocols previously reported 36,37 . A paste of the synthesized sample (80 wt.%), polyvinylidene difluoride (PVDF, 10 wt.%), and acetylene black (10 wt.%) was prepared in N-methyl pyrrolidinone (NMP).…”

Design of Ag Injection in Bi2S3 (AgBiS2) Thin Films for Photoelectrochemical Cell and Solar Cell Applications

“…Recent days, inorganic transition chalcogenide semiconducting materials are having higher attraction owing to their stability, power factor, suitable bandgap energy and sizes depending opto-electrical properties which are play a vital role in the eld of thermoelectric, catalysis, energy conversion and storage and optoelectronic devices. In this context, Ag based Bi 2 S 3 is a potential material whose direct bandgap energy is 1 eV to 1.3 eV [1][2][3][4][5][6]. Research expedite in this material progress in different applications such as linear, non-linear opto-electronic device and photoelectrode sensitizers.…”
