“…RTILs are excellent microwave-absorbing agents due to their high ionic conductivity and polarizability, thus leading to a high heating rate and a significantly shortened reaction time [35]. For these reasons, microwave-assisted room-temperature ionic liquid (MARTIL) method has been applied for the preparation of various nanomaterials [36][37][38][39]. The MARTIL method is a fast and environment friendly route to the preparation of nanostructured materials.…”

Fast, simple and template-free method is proposed for preparation of ZnO nanocrystallines in the presence of 1-ethyl-3-methylimidazolium ethyl sulfate, [EMIM][EtSO 4 ], a room-temperature ionic liquid (RTIL) under microwave irradiation. The powder X-ray diffraction (XRD) studies display that products are excellently crystallized in the form of wurtzite hexagonal structure. Energy dispersive X-ray spectroscopy (EDX) investigations reveal that the products are extremely pure. The results obtained by scanning electron microscopy (SEM) demonstrate that mean size of ZnO nanocrystallines decreases with microwave irradiation time and the RTIL content of media. Diffuse reflectance spectra (DRS) of the ZnO nanocrystallines shows blue shift relative to the bulk ZnO, which can be attributed to quantum confinement effect of ZnO nanocrystallines. A possible formation mechanism of the ZnO nanocrystallines in aqueous solution of the RTIL is presented. Photocatalytic activity of the ZnO nanocrystallines towards photodegradation of methylene blue (MB) was carried out. The results demonstrate that photocatalytic activity of the ZnO nanocrystallines increases with microwave irradiation time and the RTIL content of media.

“…RTILs are excellent microwave‐absorbing agents due to their high ionic conductivity and polarizability, thus leading to high heating rates and significantly shortened reaction times 37. Recently, the microwave‐assisted ionic liquid (MAIL) method has been applied for the synthesis of various nanomaterials, such as Co 3 O 4 , Sb 2 Se 3 , SnO 2 , CuO and CdF 2 38–42. The MAIL method is a fast and environmentally friendly route for the preparation of nanostructured materials.…”

A fast and template‐free method is proposed for the preparation of nanocrystalline ZnS in the presence of 1‐ethyl‐3‐methylimidazolium ethylsulphate, [EMIM][EtSO4], a room temperature ionic liquid (RTIL), under microwave irradiation for 4 min. Powder X‐ray diffraction (XRD) studies show that the products are excellently crystallized in a cubic structure. Energy dispersive X‐ray (EDX) spectroscopy investigations reveal that the products are extremely pure. The results obtained from scanning electron microscopy (SEM) demonstrate that nanocrystalline ZnS prepared in the presence of the RTIL are smaller than that of the sample prepared in water and the size of the nanoclusters decreases with increasing RTIL content of the media. Diffuse reflectance spectra (DRS) of the as‐prepared ZnS show a blue shift relative to the bulk ZnS, which can be attributed to quantum confinement effect of nanocrystalline ZnS. A possible formation mechanism of the nanocrystalline ZnS in aqueous solutions of the RTIL is presented. The photocatalytic activity of the nanocrystalline ZnS towards photodegradation of methylene blue (MB) was investigated. The results demonstrate that the photocatalytic properties of the nanocrystalline ZnS prepared in the presence of the RTIL are better than that of the sample prepared in water.

“…Therefore, we hypothesized that the difference between the obtained morphologies may be due to the presence of ligands, such as oleic acid and TOP, in the precursors. It is known from the literature that Sb 2 Te 3 has rhombohedral crystal structure [18]. It is suggested that, the oleic acid is passivating the longitudinal axis, leading to a smooth growth along (001) and (100) directions respectively, eventually forming the hexagonal nanoflakes.…”

Thermoelectric (TE) materials have been studied during past decades since they can generate electricity directly from waste heat. Antimony chalcogenides (Sb 2 M 3 , M = S, Se, Te) are well known as one of the promising candidates among the inorganic TE materials. We report on the synthesis of Sb 2 Te 3 nanoparticle via thermolysis method. A systematic study was done to investigate the effect of reaction time and ratio between the precursors as well as the method of cooling on the morphology and composition of obtained nanoparticles. The ratio between precursors was varied to study the effect on the morphology. Furthermore, the high purity phase Sb 2 Te 3 was obtained by a rapid cooling process.
