Structural Properties of Spinel Coal2o4 Nano-Catalysts Synthesized from Plant Extract using Green Synthesis Technique

Abstract

Spinel CoAl2O4 nanoparticles were synthesized via Aloe vera plant extract microwave heating method. Aloe vera plant extract-assisted combustion method makes straightforward synthesis, which is alternative process of preparation of spinel nanoparticles. The harmonized spinel CoAl2O4 nanoparticles was successfully characterized by powder XRD pattern, FT-IR, EDX analysis, HR-SEM analysis, and VSM techniques. XRD, FT-IR and EDS results established the development of spinel and single cubic phase CoAl2O4 nanocrystals. The formation of spherical shaped nanoparticles was affirmed by HR-SEM technique. VSM measurements revealed that CoAl2O4 sample have superparamagnetic behavior.
