Synthesis and characterization of aluminium oxide based al2o3 x x cuo mgo ceo2 and bi2o3 binary metal oxide nanocomposites

Abstract

In present scenario, Technology based on nanomaterials applications is at top positions. The materials have colourful contrast size dependent properties at nanoscale due to its large surface to volume ratio. The thesis work titled Synthesis and characterization of Aluminium Oxide based Al2O3-X (X= CuO, MgO, CeO2 and Bi2O3) Binary metal oxide nanocomposites has explored the synthesis mechanism of Al2O3 based nanocomposities and thereafter, its characteristics results were analyzed in various patterns. The chapter one reviews a general introduction of nanomaterials. Introduction of nanomaterials and their unique properties are discussed in brief. The prevalent techniques for synthesizing nanomaterials, as well as their potential applications, are also discussed in this section. It also discussed in detail the importance of Aluminium Oxide nanomaterials. The Chapter second summarized the past research work that has been done already in this field and mentioned a number of quoted research papers. The review of literature is useful in the selection of the entitlement. The Al2O3 nanostructured material and its binary nanocomposites (NCs) with different concentration were synthesized by using advance co-precipitation techniques. The details of synthesis mechanism and characterization approaches were elaborated in chapter three of thesis. The effect of calcination temperatures at fixed dopant concentration 10% have been studied at different temperatures, 473K, 673K, and 873K for fixed duration of two hours. The impact of different dopant concentrations, namely 5%, 10%, and 20%, has been examined under a fixed calcination temperature of 600°C for duration of two hours. The viii respective results of study have been explained in chapter four to chapter eight of the thesis. The analysis of effect of calcination temperature on pure Al2O3 nanostructured material shows that all the samples were synthesized at nanosized scale range from 19 nm to 34 nm. The dopant MgO in Al2O3 (alumina) NSM at 5%, 10% and 20% concentration have
