Synthesis and Characterizations of Ce0.5Sr0.5Co0.8Fe0.2O3-? (CSCF)Solid Oxide Fuel Cell Cathode Material by Sol-Gel method

Synthesis and characterizations of CoTiO3-clay nanocomposites by sol-gel method

CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°C for 2 hours. The presence of rhombohedra phase of CoTiO3 in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration .The optimum condition ...

Synthesis and Characterizations of Silica Nanoparticles by a New Sol-Gel Method

Silica nanoparticles were synthesized by chemical methods from tetraethylorthosilicate (TEOS), polyethylene glycol 5% and hydrochloric acid 0.001 N. The sol-gel process was applied for the preparation of nano silica gel. This method is hydrolysis and condensation reactions of TEOS as precursor of silica. The optimal synthesis conditions for the preparation of silica nanoparticles were obtained ...
