Preparation and Evaluation of NiFe204 and CuFe204 Nanoeatalysts by Combination of Sol- Gel Auto-Combustion Method and Irradiation Technique
نویسندگان
چکیده مقاله:
The dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. Cu and Ni Unites nanocatalyst powders sithcomposition of Caned], and NiFe204 were synthesized by a sol-gel auto catalnic combustion process. Themolar ratio between metal ions and urea was 11.2. The sob gel process was done at 80 °C. The nanopaniclecrystallines have been calcined at 800 °C.Combustion behavior and crystallite size of synthesized powders were investigated iyith the help of ScanningElectron Microscopy observation and X-ray diffraction technique. X- ray diffraction and Scanning ElectronMicroscopy were carried out for charactenzation of the powders. The grain size of the prepared femte powdersis found lobe in the range 30-35 mu_

متن کاملSynthesis of ZrO2 nanoparticle by combination of sol-gel auto-combustion method- irradiation technique, and preparation of Al-ZrO2 metal matrix composites
Nanocrystalline ZrO2 with particle size of about 38 nm was directly synthesized by sol-gel auto-combustion method. The overall process involved three steps: formation of homogeneous sol at 50-55°C; formation of dried gel at 110°C, and combustion of the dried gel at 400°C. Experiments revealed that ZrO2 dried gel derived from glycine (Fuel) and nitrate sol exhibited self pr...

متن کاملSynthesis and characterization of nanocrystalline spinel Zinc ferrite prepared by sol-gel auto-combustion technique
Sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. In this work, nanosize (d) powders with compositions of ZnFe2O4 were synthesized by sol–gel combustion method. The puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦C for 4 h. These powders are characterized by X-ray diffraction and scanning electron microsco...
