P(AA)‐Ag heterogeneous catalyst system comprised of Ag nanoparticles embedded within hydrogel matrices has been described for the selective aerobic oxidation of alcohols and reduction of nitro phenols in water. P(AA)‐Ag nanocomposite was characterized by Fourier transform infrared (FT‐IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermal gravimetric analysis (TGA), X‐Ray photoelectron spectroscopy (XPS) and inductively coupled plasma atomic emission spectrometer (ICP). Catalytic activity of p(AA)‐Ag catalyst was investigated in the aerobic oxidation of primary alcohols and reduction of nitro compounds by emphasizing the effect of different parameters such as temperature, catalyst amount, substituent effect, etc. The catalyst was easily recovered from the reaction medium and it could be re‐used for other three runs without significant loss of activity.

“…To achieve the high performance of catalyst, enhancement of the surface area of catalyst and controllability of the size and structure of active sites are important [3][4][5]. Various attempts have been made to synthesize and control the morphology of Pd-based nanoparticles (NP) using complicated procedures, such as polyol process and thermolysis of Pd complexes [6][7][8][9]. However, NP made by these methods usually leads to the agglomeration by van der Waals force or sintering bonds, resulting in the reduction of active sites and the limitation of catalytic activity and selectivity [10,11].…”

A sonochemical method has been employed for the synthesis of palladium oxide (PdO) nanoparticles deposited on silica nanoparticle. By sonochemical process, the PdO nanoparticles were doped on the surface of silica at room temperature and atmospheric pressure with short reaction time. Silica nanoparticles were used as a supporting material to suppress aggregation and thereby to increase surface area of PdO nanoparticles. Fabricated PdO-doped silica nanoparticle (PdO@SNP) was applied as a nanocatalyst for selective alcohol oxidation reaction in the presence of molecular oxygen. The PdO@SNP composite showed higher catalytic activity and selectivity than unsupported PdO nanoparticle for aerobic alcohol oxidation reaction.

“…Properties of nanoparticles, especially the photoluminescent properties, have been a subject of extensive investigations. There are a range of methods of producing metallic nanosized materials, including radiation methods, thermal decomposition, chemical vapor deposition, reduction in microemulsions and chemical reduction methods [32][33][34][35][36]. However, most of these techniques tend to be expensive and time-consuming.…”

A new tin complex, [l-(4-bpdb){Me 2 Sn(cupf) 2 } 2 ] (1), was prepared by reacting dimethyltin(IV) dichloride, with 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene (4-bpdb) and cupferron in a fast and facile process. The complex was fully characterized based on its 1 H and 13 C NMR, IR, and UV spectra and elemental analysis. The nanostructure of the prepared compound was synthesized by the sonochemical method. The new nanostructure was characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), IR spectroscopy and elemental analysis. Thermal stability of single crystalline and nanosize samples of the prepared compound was studied by thermal gravimetric and differential thermal analysis. The prepared complexes, as bulk and as nanoparticles, were utilized as a precursor for preparation of SnO 2 nanoparticles by direct thermal decomposition at 600°C in air. The morphology and size of the SnO 2 nanoparticles were determined by scanning electron microscopy, XRD and IR spectroscopy and the results showed that particle size of the SnO 2 nanoparticle depend on the initial particles size of 1. Photoluminescence properties of the nanostructured and crystalline bulk of the prepared complex and SnO 2 nanoparticles core of them were investigated.
