A novel AgO/ZnO/HY-zeolite bimetallic nanocatalyst was designed and synthesized by an impregnation method. The purpose of this to remove dibenzothiophene as the primary sulfur content from a model light gasoil in catalytic oxidative desulfurization (ODS) process. characteristics were determined Fourier transform IR spectroscopy, Brunauer-Emmett-Teller analysis, scanning electron microscopy, X-r...

a new magnetic nanocatalyst has been prepared using immobilization of vanadate onto aminopropyl functionalized sio2/fe3o4(vo3-/nh3+-sio2/fe3o4). the obtained magnetic catalyst was characterized by ft-ir, xrd, vsm and sem techniques and used for sulfoxidation of sulfide compounds to the correspondingsulfoxides in presence of h2o2 as oxidant at room temperature. the optimum of reaction conditions...

A highly active and stable nano structured Pt/Mg1-xNixO catalysts was developed by a simple co-precipitation method. The obtained Pt/Mg1-xNixO catalyst exhibited cubic structure nanocatalyst with a size of 50-80 nm and realized CH4 and CO2 conversions as high as 98% at 900°C with excellent stability in the dry reforming of methane. The characterization of catalyst was performed using various ki...

PtRu/C nanocatalysts were prepared by changing the molar ratio of citric acid to platinum and ruthenium metal salts (CA:PtRu) from 1:1, 2:1, 3:1 to 4:1 using sodium borohydride as a reducing agent. Transmission electron microscopy analysis indicated that well-dispersed smaller PtRu particles (2.6 nm) were obtained when the molar ratio was maintained at 1:1. X-ray diffraction analysis confirmed ...

New NiO-ZrO(2) nanocrystals (MNZ-1) with mesoscopic self-assembly have been synthesized by using a non-ionic surfactant as the structure directing agent (SDA) via evaporation induced self-assembly (EISA) method. Powder X-ray diffraction (PXRD), N(2) sorption study and transmission electron microscopic (TEM) image analyses revealed the cubic structure, mesoporosity and mesoscopic self-assembly o...

Encouraged by our recent success in work with POMs as green catalysts, we have developed our research in field of nanotechnology. Sodium 30-tungstopentaphosphate, so called Preyssler anion, nanoparticles were synthesized and the morphology and size of these nanoparticles were characterized using, transmission electron microscopy (TEM), scanning electron microscopy(SEM), X-ray diffraction(XRD) a...

Calcium oxide (CaO) nanoparticles are known to exhibit unique property due to their high adsorption capacity and good catalytic activity. In this work the CaO nanocatalysts were prepared by hydrothermal method using anionic surfactant, sodium dodecyl sulphate (SDS), as a templating agent. The as-synthesized nanocatalysts were further used as substrate for the synthesis of alumina doped calcium ...

Research on the synthesis of nanomaterials using metal-organic frameworks (MOFs), which are characterized by multi-functionality and porosity, as precursors have been accomplished through various synthetic approaches. In this study, copper and copper oxide nanoparticles were fabricated within 30 min by a simple and rapid method involving the reduction of a copper(II)-containing MOF with sodium ...
