Effect of Iron Doping of Structural and Magnetic Activity on Iron Aluminate Nano-Materials by Microwave Irradiated Chemical Co-Precipitation Protocol

Abstract

In present work designates the preparation of nanocrystalline Iron dopped Alumina nanoparticles with general formula Al₂Fe₂O₆-µ prepared by microwave irradiated chemical co-precipitation protocol. The structural (XRD and FTIR), morphological (FESEM, HRTEM) and magnetic properties of the products were characterized. The XRD results explores that the prepared nano-particles lies in nano-region and obey  hexagonal crystalline nature. The FTIR spectrum of 10% Iron Oxide incorporated Aluminium Oxide, calcined at various temperatures 200^oC, 400^oC and 600^oC for 2hrs.The IR results reveals that broad band spanning 3500 cm- to 3330 cm-1 and another wide band between 1700 cm-1 and 1500 cm-1 were corresponds to hydroxyl ion vibration of water present in atmosphere moisture. The peaks at 827 cm-1 and 504 cm-1 are associated with metal oxide (MOs) vibrations, such as Al-O-Al in the Al₂O₃ and O-Fe-O of Fe₂O₃ nanostructures. The FESEM images of Fe₂O₃ dopedAl₂O₃ nano-structured substances calcined at 600⁰C/2hrs that substance are homogenous in size, cluttered in macrocosm and truncated spherical in contour. Observation of the HRTEM images explores that the dimensions of the nano-structured substances lies in confine of 30 nm to 35 nm and aggregate grain size determined out 32 nm. There upon the HRTEM summary are in accordance with those of XRD outcomes.
