Synthesis of binary copper chalcogenides by mechanical alloying

Simple synthesis of zinc sulfide and cadmium sulfide under hydrothermal conditions

“…Both of the two methods have advantages and disadvantages. Reactions between elements in a sealed tube are simple but needs high temperature 1), 2) or long time milling 3) in order to get pure metal sulfide. For example, copper is very reactive with sulfur and their reaction starts even at room temperature.…”

Sonochemical Synthesis of Copper and Silver Chalcogenides

“…Recently, we prepared many chalcogenides of Cu, Ag, and Sm by milling mixtures of the elements using a planetary ball mill (2,3). The notable results are that the metastable high-pressure phases of tetragonal Cu \V S and pyrite-type CuSe were prepared by MA (2). These are the first preparations of high-pressure phases by MA.…”

Ultrasound mediated synthesis of CuS nanocrystallites

“…Again, CuS maintains transmittance in the infrared region and shows low reflectance in the visible and high reflectance in the near-infrared region, which makes it an important material for solar energy absorption [33]. Different methods of synthesis of copper sulphides reported earlier include synthesis from elements at elevated temperatures [34,35], microwave-assisted methods [36,37], thermolysis of molecular precursors [38,39], hydro/solvothermal synthesis [40][41][42][43], microemulsion synthesis [44] and mechanochemical preparation methods [45,46]. The nanoparticles prepared by the mentioned processes require high temperature and also long duration of the reaction.…”
