Preparation and Investigation of Spinel-structured FeCo2O4 Nanoparticles as an Efficient Catalyst for Oxidation of Sulfides
We report the preparation and characterization of spinel-structured FeCo2O4 nanoparticles for the efficient and selective oxidation of sulfides. The as-prepared FeCo2O4 nanoparticles were characterized by powder X-ray diffraction (PXRD), energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). According to TEM images, the size of the...
متن کاملNanoZnO as an efficient & reusable catalyst for the preparation of 1,4-DHPs via Hantzsch reaction
Easily prepared nanoZnO was found to be as an efficient catalyst in the synthesis of 1,4-DHPs via four-component reaction of 1,3-dicarbonyls, aldehydes and ammonium carbonate in water at 60 °C. The prepared nanoZnO was characterized by XRD and FT-IR analysis, while the determined specific surface area of nano catalyst by BET method was 33 m2/g.

متن کاملA Convenient Procedure for Friedlander Synthesis of Quinoline Derivatives Catalyzed by Zirconium Dodecylphosphonate as an Efficient and Reusable Catalyst
2-Amino-substituted ketones react with α-methylene ketones under solvent-free conditions at 90 °C in thepresence of a catalytic amount of zirconium dodecylphosphonate to create the corresponding quinolinesin excellent yields. This procedure recommends numerous advantages such as easy work-up, use of mild,reusable and safe catalyst, short reaction timeand high yields. The new compounds have been...
