In the past decades, many methods have been developed to synthesize zero- dimensional  nanoparticles, quasi–one–dimensional (1D) CuO nanostructures, such as metal organic deposition technique,  microwave irradiation, sol-gel-like dip  technique, reverse micelle-assisted route, chemical method, and simple template free solution route. Among those synthesis methods, hydrothermal and chemical reac...

In this work, a series of palladium supported on the La0.8Sr0.2MnO3.15 perovskite catalysts (Pd/LSM-x) with different Pd loading were prepared by microwave irradiation processing plus incipient wetness impregnation method and characterized by XRD, TEM, H2-TPR and XPS. These catalysts were evaluated on the lean CH4 combustion. The results show that the Pd/LSM-x samples prepared by microwave irra...

This paper describes the details of synthesizing nano crystalline YBCO superconductor using a sol-gel combustion method and the effect of sol pH and sintering temperature on particle size was investigated. The sintering temperature was chosen 880°C and the samples were annealed at this temperature for 5 hours. The morphology and structure of the nano scale products were characterized by powder ...

TiO2/Al-MCM-41 composites with various titania content were prepared by loading titania into the mesopores of Al-MCM-41 mesoporous molecular sieve from coal-measure kaolin as silicon and aluminum source via general sol-gel method and incipient wetness impregnation method. TiO2/Al-MCM-41 composites were characterized by XRD, FT-IR and SEM, and the photocatalytic degradation of methyl orange solu...

Abstract TiO 2 thin films modified with MoO 3 nanostructures were obtained by the spin coating technique. The precursors solutions prepared sol-gel technique adding colloids of Mo-based laser irradiation powders suspended in liquid media. It was found that layered form colloidal solutions. characterized X-Ray Photoelectron, Raman, Ultraviolet– Visible and PL Spectroscopies, Scanning Electron Mi...

Diamond is synthesized under the atmospheric pressure and ambient temperature conditions in present research that aims to construct in-liquid synthesis technique. The developed technology obtained results for an method (iLS method) are as follows; acetone (organic solvent) dissolves polystyrene, KOH aqueous solution decomposes gelatin/cocoon or rice. active carbons (included free carbon) organi...

Nanocomposite zinc ferrites were synthesized using glycine-nitrates by sol–gel auto-combustion technique. The influence of calcination temperatures varying from 400 to 900°C on structural and magnetic properties of spinel ZnFe2O4 powders have been investigated. The characterization measurements including X-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetomet...

Abstract The uses of phosphate based luminescent materials are presented in this study different fields luminescence. There types phosphors available the field luminescence such as borates, sulphates, fluorides, sulphides, phosphates etc. From all these phosphors, phosphate-based shows their potential almost every last few years and it becomes a key material especially photoluminescence, thermo...
