Montmorillonite/ZrO2 nanocomposites were prepared by the sol-gel method underultrasonic irradiation. The montmorillonite was incorporated into Zirconium gel. After stirring for 24 hr, the mixture was irradiated for 30 min under ultrasonic irradiation. The filtrated composite gel was calcinated at 400°C for 3h in furnace. The morphology of prepared catalysts was characterized by field emis...

α-Fe2O3 (hematite) nanoparticles were synthesized using tragacanth gel as biotemplate andiron chloride as the iron source by the sol-gel method. This method has many advantages suchas nontoxic, economic viability, ease to scale up, less time consuming and environmentalfriendly approach for the synthesis of α-Fe2O3 nanoparticles without using any organicchemicals. Nanoparticles were characterize...
