Structural variations in zinc(II) complexes with N,N-di(4-fluorobenzyl)dithiocarbamate and imines: New precursor for zinc sulfide nanoparticles

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

“…1 The cubic structure is stable at low temperature and in bulk ZnS it is converted to the high temperature stable hexagonal phase at temperatures above 1000°C, however, for nanocrystalline ZnS, a cursor molecule is then converted into the metal sulfide by a chemical reaction, in most cases initiated by a thermal treatment. 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.…”

Photocatalytic Degradation of Single and Binary Mixture of Brilliant Green and Rhodamine B Dyes by Zinc Sulfide Quantum Dots

“…Biogenic ZnS quantum dots photodegraded 88% of organic dyes under sunlight after 8 h [27]. However, most of the reports on the use of ZnS quantum dots as photocatalysts showed that they suffer from low photodegradation efficiency [28][29][30]. Hence, the search for highly efficient ZnS quantum photocatalysts is a continuing effort.…”
