A series of Fe3O4 supported on mesoporous FDU-12 silica systems were prepared by the hydrothermal conditions. The surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like FTIR, XRD, N2 adsorption–desorption and TEM. XRD and adsorption–desorption analysis shows that the mesostructure of FDU silica remains intact after Fe3O4 modifications, while […]
In situ electropolymerization as a facile synthetic procedure has been used to obtain highly active compositesof ionic liquid functionalized graphene oxide(FGO)and poly ortho aminophenol (POAP). Surface and electrochemical analysis have been used for characterisation of FGO-POAP composite film. Nickel was accumulated by complex formation between Ni (II) in solution and amines sites in the polymer […]
The synthesis of pharmaceutically and biologically active 2-amino-4H-chromenes was described using TiO2/nanoclinoptilolite (TiO2/NCP) as an efficient nanocatalyst under solvent-free condition. The TiO2/NCP was fabricated through modification of NCP with HDTMA, then the surface modified NCP was impregnated with titanium tetrachloride solution. Finally, the material incorporated with titanium was calcinated at 500 ºC and was characterized […]
Fe (III) supported graphitic carbon nitride nanocomposite was synthesized by impregnation of FeCl3 with g- C3N4 (Fe (III)@g-C3N4). Then, the synthesis of spirooxindole derivatives was carried out in the presence of Fe (III) @ graphitic carbon nitride nanocompositevia the multi-component reaction of malononitrile, isatins, and 1,3-dicarbonyl compounds in green media (ethanol/water (1:1)) under reflux conditions […]
Due to the pollution of dyeing and textile industry wastewaters in different colors and the need to remove these pollutants from the wastewaters, it is necessary to study and develop effective and efficient technology solutions required. To remove dye from aqueous solutions, photodegradation is employed as an effectively simple way. Thus, the BiOBr photocatalyst was […]
Porous ZnO-hydroxyapatite nanocomposite was prepared by dissolution of a rock phosphate ore in an acidic medium followed by alkaline precipitation. Its photocatalytic activity was assessed for the degradation of paracetamol as one of the most commonly prescribed pharmaceutical drugs and methylene blue as dye model. Thanks to its good porosity, the 40ZnHAp nanocomposite adsorbed the […]
The Cu(II) complex of 2,6-pyridine dicarboxylic acid (PydcH2, dipiconilic acid) was successfully prepared and readily trapped in the nanocavity of zeolite-X (NaX) through a flexible synthetic method. The characterization of nanocomposite ([Cu(pydcH2)(pydc)]-NaX) was performed by FT-IR, XRD, BET isotherm, SEM, TEM, and elemental analysis, that approved the encapsulating of coordination compound in the channels of […]
A supported magnetic nanocomposite as a simple, stable, and efficient catalyst was successfully developed for condensation reaction of aldehydes, ammonium acetate, and isatoic anhydride to prepare 2,3-dihydroquinazolin-4(1H)-one derivatives as essential biologically active heterocyclic compounds. Ethanol as a non-toxic solvent under a reflux condition was utilized in the reactions. The Fe3O4/SiO2/CeO2 nanocomposite was prepared as a […]
The selective oxidation of olefins is a key academic and industrial research challenge. Herein, silver was supported on mesoporous silica through a facile synthesis procedure, and characterized using various technics such as FT-IR, XRD, SEM, BET, and EDX. This efficient separable agent alongside aqueous H2O2 was applied to the oxidation of various olefines (1-octen, 1-hexene, […]
The sol-gel technique is employed for the synthesis of tungsten trioxide (WO3) nanosheets. The Au/WO3 nanocomposite is prepared using laser ablation employing an Nd-YAG laser operating at a wavelength of 1064 nm and utilizing gold metal. The SEM images demonstrate that WO3 was formed as nanosheets with a thickness between 36nm and 80nm. X-ray diffraction […]
