Plant Extract Assisted Green Synthesis and Structural Studies of Spinel Nial2o4 Nano-Catalysts

Spinel NiAl2O4 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 spinel preparation. The synthesized spinel NiAl2O4 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 NiAl2O4 nanocrystals. The formation of spherical shaped nanoparticles was affirmed by HR-SEM technique. VSM measurements revealed that NiAl2O4 sample have superparamagnetic behavior.
