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 8...

The role of iron in two modes of integration into alumina catalysts was studied at 0.39 wt% Fe and tested in trichloroethylene combustion. One modified alumina was synthesized using the sol-gel method with Fe added in situ during hydrolysis; another modification was performed using calcined alumina, prepared using the sol-gel method and impregnated with Fe. Several characterization techniques w...

Metal and metal oxide nanoparticles (NPs) have piqued the interest of material scientists in recent years due to their unique physicochemical properties which are dependent on size, shape, chemical surroundings. The sol gel combustion is one most straightforward practical technique for getting tiny similar size shape powder out all current lead nanoparticle synthesis techniques. In this study, ...

The intent of begun work is to synthesis and study the structural, electric, magnetic frequency dependent dielectric properties Ni0.6Cd0.4Fe2O4 NPs fabricated via sol-gel auto-combustion technic. XRD data affirmed that synthesized do possess a single phase; spinel structure; cubic geometry ferrite in nature. lattice constant (a) was estimated be 8.363 Å crystallite size (t) determined from Deba...

ZnO and Mn-ZnO nano powders were prepared by the sol-gel auto combustion method. The products were characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and Mn-doped ZnO was obtained 44 and 51 nm, respectively. ...
