“…Finally, the In2S3-coated Cu nanoparticles were transformed into CuInS 2 nanoparticles by heating them at 300 o C for 2 h. Thus, our synthesis process for CuInS2 nanoparticles preparation was found relatively very mild and simple in comparison to other methods to prepare CuInS2 nanoparticles such as solvent thermolysis, 2,4,34-40 hydrothermal route, 5,7,41 and microwave irradiation. 42 …”

CuInS2 nanoparticles were synthesized by a simple sonochemical method; First, Cu nanoparticles were prepared from CuCl2 in methanol solution by a one pot reaction through the sonochemistry under multibubble sonoluminescence (MBSL) conditions. Second, the resulting Cu nanoparticles were treated with InCl3․4H2O and CH3CSNH2 (thioacetamide) at the same MBSL conditions to synthesize In2S3-coated Cu nanoparticles in methanol solution. Then, they were transformed into CuInS2 (CIS) nanoparticles of 20 ~ 40 nm size in diameter by thermal heating at 300 o C for 2 hr. The prepared CIS nanoparticles, of which band gap is 1.44 eV, were investigated by X-ray diffractometer, UV-Vis spectrophotometer, inductively coupled plasma spectrometer, and high resolution-transmission electron microscope.

“…[25] CuInS 2 occurs naturally as the rare mineral roquesite in high-temperature hydrothermal veins, usually in the form of inclusions in chalcopyrite (CuFeS 2 ), sphalerite (ZnS) or bornite (Cu 5 FeS 4 ). [26] Synthesis of CuInS 2 has been achieved via a number of methods, including solidstate reaction, [27] solvothermal synthesis, [28] static hydrothermal synthesis, [29] chemical vapour deposition [22,30,31] and spray pyrolysis. [32] The application of CuInS 2 in photovoltaic devices requires the production of pure, good quality thin films, [24] but the cost of synthesis remains a major drawback for widespread use.…”

Replacement reactions ('pseudomorphism') commonly occur in Nature under a large range of conditions (T 25 to >600 ˚C; P 1 to >5 kbar). Whilst mineral replacement reactions are often assumed to proceed by solid-state diffusion of the metal ions through the mineral, many actually proceed via a coupled dissolution and reprecipitation (CDR) mechanism. In such cases, a starting mineral is dissolved into a fluid and this dissolution is coupled with the precipitation of a replacement phase across the reaction front. In cases where there are close relationships between the crystal structures of the parent and newly formed minerals, the replacement can be topotactic (interface-coupled dissolution and reprecipitation). The kinetics and chemistry of the CDR route are fundamentally different from solid-state diffusion and can be exploited i) for the synthesis of materials that are often difficult to synthesise via traditional methods and ii) to obtain materials with unique properties. This review highlights recent research into the use of CDR for such synthetic challenges. Emphasis has been given to i) the use of CDR to synthesise compounds with relatively low thermal stability such as the thiospinel mineral violarite ((Ni,Fe) 3 S 4 ), ii) preliminary work into use of CDR for the production of roquesite (CuInS 2 ), a potentially important photovoltaic component and, iii) examples where the textures resulting from CDR reactions are controlled by the nature and texture of the parent phase and the reaction conditions; these being the formation of micro-porous gold and three-dimensional ordered arrays of nanozeolite of uniform size and crystallographic orientation.

“…Up to now, different synthetic methods have been investigated for the preparation of CuInS 2 nanostructures. Besides solid state reaction [4], various solution-based routes such as oleylamine route [5], solvothermal and hydrothermal routes [6,7], and single-source precursor method [8] have been applied. In particular, colloidal synthetic routes using suitable capping agents [9,10] have been heavily investigated, in recent years.…”

This investigation reports synthesis of CuInS 2 nanoparticles with the aid of (1,8-diamino-3,6-dioxaoctan)copper(II) sulfate ([Cu(DADO)]SO 4 ), bis(propylenediamine)copper(II) sulfate ([Cu(pn) 2 ]SO 4 ) complexes, and thiosemicarbazid in the presence of microwave irradiation. Besides, sodium dodecyl sulfate and propylene glycol are used as capping agent and solvent, respectively. In this method, microwave irradiation creates the activation energy for dissociation of the precursors and leads to the CuInS 2 nanoparticles formation. The effect of preparation parameters such as microwave power, irradiation time, and type of copper precursor on the particle size of products is studied. XRD results indicate that pure tetragonal phase CuInS 2 can be only obtained after annealing at 400°C for 2 h in a gas mixture of 85 % Ar and 15 % H 2 . SEM images show that with decreasing the microwave power and irradiation time, particle size of CuInS 2 nanoparticles decrease. On the other hand, the particle sizes of CuInS 2 nanoparticle synthesized by [Cu(pn 2 )]SO 4 are lower than that of [Cu(DADO)]SO 4 due to its further more steric hindrance effect. Additionally, the photovoltaic measurements of the products show that the efficiency of the devices made by CuInS 2 nanoparticles are between 0.12 and 0.26 %.
