A new solvothermal method for the synthesis of thiol-protected silver nanoparticles starting from silver thiolates is reported. The method has been tried with thiols of different chain length, such as octane and octadecane thiols, and the particle size was found to be nearly the same for both molecules. The synthesis was dependent on heating conditions and the best results were obtained when th...

In this paper, uniform hydroxyapatite (HA) nanowires of width 60 nm and length 1 μm are synthesized by solvothermal synthesis. The formation process of the nanowires has been elaborated from the structure within the reverse micelles by the time-resolved fluorescence quenching technique. The results reveal that the formation of amorphous nuclear/surfactant complex and the electrostatic field wit...

This review focuses primarily on the past 10 years of our development of multifunctional coordination polymers with 1D, 2D and 3D structures employing low-temperature and cost-effective hydrothermal and solvothermal methods. The effects of the experimental conditions and parameters on the crystal formation and phase separation, including temperature and pressure, reaction pH, solvent and compos...

Ceria is a technologically important material with applications in catalysis, emissions control and solid-oxide fuel cells. Nanostructured ceria becomes profoundly more active due to its enhanced surface area to volume ratio, reactive surface oxygen vacancy concentration and superior oxygen storage capacity. Here we report the synthesis of nanostructured ceria using the green Deep Eutectic Solv...

The aim of this work was to characterize copper ferrite nanoparticles synthesized via solvothermal method and to investigate the effects of ultrasonic waves on the synthesis efficiency. Crystal structure, functional groups, microstructure, particle size, magnetic properties, specific surface area, porosity distribution and photocatalytic activity of the synthesized nanoparticles were also inves...

Selective synthesis of titanium dioxide (TiO2) polymorphs including anatase, rutile, brookite and TiO2(B) by solvothermal treatment of water-soluble titanium complexes is described with a special focus on their morphological control. The utilization of watersoluble titanium complexes as a raw material allowed us to employ various additives in the synthesis of TiO2. As a result, the selective sy...
