A novel sonochemical synthesis and nanostructured assembly of polyvinylpyrrolidone-capped CdS colloidal nanoparticles

In-situ precipitation synthesis of novel BiOCl/Ag2CO3 hybrids with highly efficient visible-light-driven photocatalytic activity

“…As shown in Fig. 6, the broad and strong peak in the range of 3200-3550 cm -1 may belong to the stretching vibrations of -OH of adsorbed water molecules, while, the obvious absorption at 1637 cm -1 can be ascribed to deformation vibrations of the -OH groups of adsorbed water molecules [31]. For pure Ag 2 CO 3 , the peaks appearing at 1386 and 887 cm -1 are attributed to the characteristic absorption bands of CO 3 2- [32].…”

Solvothermal synthesis of CdS QDs/MWCNTs nanocomposites with high efficient photocatalytic activity under visible light irradiation

“…The peak ranged from 1120 to 1000 cm -1 could be attributed to the C-O of ethanol that might come from the washing process. Additionally, the absorption peaks ranged from 1286 to 1500 cm -1 , which could be assigned to the framework vibration of the heterocycle in PVP [34]. All these observations indicated evidently that CdS QDs were attached on the surface of MWCNTs successfully.…”

Phase Controlled Monodispersed CdS Nanocrystals Synthesized in Polymer Solution Using Microwave Irradiation

“…Nanometric semiconductor particles exhibit unique size-tunable optical and electronic properties such as band gap widening, change of electrochemical potential of band edge, enhancement of photocatalytic activities with decreasing crystallite size [3][4][5][6][7][8][9][10]. These properties are due to the large number of surface atoms and the three-dimensional confinement of electrons [11,12]. They are useful for various applications such as solar cells, photovoltaics, photodetectors, electronic memory devices, chemical sensors, light-emitting diodes, optoelectronic devices, photocatalysis, single charge memories, lasers, luminescent nanocomposites and diagnostic agents in medicine, gas sensor and so on [8,[13][14][15].…”

“…They could offer a direct function to prevent agglomeration of the nanoparticles and improve their optical properties and their stability [6,8,18]. However, to get well defined and optimized properties, it is necessary to have control over both of the nanocrystalline structure, morphology and the crystal size in synthesizing nanoparticles and having a narrow size distribution [11,19].…”
