In this investigation nickel-cadmium ferrite nanoparticle with stoichiometric composition of Ni0.3Cd0.7Fe2O4 was synthesized by Sol-gel auto- combustion method. In order to study the effect of particle size on physical properties of samples, the powder samples was annealed at temperatures 350, 400, 450 and 500 ○ C for 3h. Structural, morphological and magnetic properties of samples were analyze...
CO2 (dry) reforming of methane (DRM) is a significant and useful reaction from the standpoint effective utilization conversion two main greenhouse gases to value-added synthesis gas. To achieve highly efficient stable DRM reaction, Silicalite-1-encapsulated ultrafine Ni nanoparticle catalyst (Ni@S-1)by using phyllosilicate (Ni-PS) as precursor was newly developed. This Ni@S-1 exhibited negligib...
The utilization of nanoparticle in ethanol-diesel emulsions combustion catalyst is important. For this study, ethanol and diesel fuels are emulsified varying the amount as 5, 10, 15% volume ratio designated E5, E10, E15, respectively, by using span 80 tween emulsifying agents. Nickel Zinc Iron Oxide (NiZnFe2O4) used each fuel sample with a dose rate 25, 50, 100 ppm. Cetyl Trimethyl Ammonium Bro...
Metal nanoparticle synthesis using plant extracts has gained a lot of attention because its ease-of-use, environmental friendliness and simplicity. In this study, nickel nanoparticles were synthesized an aqueous extract Moringa oleifera leaves in one-step technique. The formation was confirmed UV-visible spectroscopy, XRD, SEM EDS, FTIR spectroscopy showed that these may be reduced to chloride ...
