Abstract:
Nano-sized alumina oxide (Al₂O₃) nanoparticles (NPs) have been successfully synthesized by chemical precipitation method using aluminum nitrate as precursor and citric acid as reducing agents. Precipitation method of synthesizing Al₂O₃ is most efficient and simplest process using inexpensive raw materials, produces less pollution, and has several advantages such as purity, thermal stability and homogeneous nanoparticle in size. The synthesized NPs have been characterised by UV-vis, SEM, FTIR, AFM and XRD. Result of UV-vis and FTIR confirms the formation of aluminum oxide NPs. XRD peaks show the grain size of aluminum oxide NPs. Scanning electron microscopy (SEM) reveals that the particle size of the particles lies between 30 and 90 nm.
