dc.description.abstractMetal Matrix Composites (MMCs) have evoked an intense interest in recent times for potential applications in marines, aerospace and automotive industries owing to their larger strength to weight ratio and high-temperature resistance. We have synthesized nanocomposites of (LaMnO3)1-x/(TiO2)x and (Fe2O3)1-x/(Cr2O3)x with varying concentration of TiO2 (x = 0.0-0.4) and Cr2O3 (x = 0.0-1.0). In the first chapter, includes the introduction of the metal matrix nanocomposites and their advantages. In the second chapter we have discussed about the literature review and knowledge gap. Chapter 3 involves the experimental procedure and discussion of different characterization techniques (XRD, FTIR, FESEM and EDS) used to study the prepared sample. Chapter 4 involves result and discussions obtained by characterizing the prepared sample. XRD analysis confirms the orthorhombic structure of (LaMnO3)/(TiO2) and rhombohedral structure (Fe2O3)/(Cr2O3) nanocomposites. From FESEM we have calculated the particle size for pure (LaMnO3) is 1 m and for (LaMnO3)1-x/(TiO2)x and its value decreases from 19.99- 16.91 nm with increase the concentration of TiO2 from x = 0.1-0.4. We have also calculated the band gap and refractive index from the FTIR analysis and found that gradual increase in band gap from 2.1-2.26 eV and decrease in refractive index from 2.67-2.62 as the concentration of TiO2 increases (x = 0.0-0.4). The (Fe2O3)/(Cr2O3) iv nanocomposites showed that increase in band gap 2.1-3.0 eV with decrease in particle size from 70.71-49.24 nm and refractive index from 2.67-2.44 as the concentration and Cr2O3 increases (x = 0.0-1.0.) The FTIR confirms all the functional groups present in the synthesized samples. The main application of these as- synthesized nanocomposites is photocatalysis.en_US
