Exploration of Biomedical and Phtotocatalytic Properties of Transition Metal Oxide Nanocomposits

Abstract

Metal oxide NCs represent a cutting-edge class of materials formed by combining metal newlineoxides or other substances, often at the nanoscale. Introducing other elements into metal oxides can further tailor their electronic structure, leading to improved performance in biomedical applications, catalysis, or sensing. This research primarily focuses on the synthesis, characterization, and applications of CuO/Cu2O-ZnO, CuO-Co3O4, and CuO-NiO NCs using the leaf extract of Ipomoea carnea and Commelina benghalensis leaf extract. In essence, metal oxide NCs present a promising avenue for addressing diverse technological challenges and fostering innovation across multiple domains.. Chapter 1 of the thesis provides a comprehensive introduction to NPs, classification, and Cu, Zn, Ni, and Co oxide NCs.. This chapter summarizes the characteristics of these materials and how they correlate with their various applications. Chapter 2 provides an extensive literature review on metal oxide NCs, exploring their diverse applications across various fields. It delves into the multifaceted utility of NCs, highlighting their versatility. In Chapter 3, the focus moves to the materials and methodologies employed for synthesizing NCs. This chapter discussed in detail the extraction of leaf extract from Ipomoea carnea and Commelina benghalensis, and the synthesis of 90:10, 80:20, and 70:30 CuO/Cu2O-ZnO, CuO/Cu2O-NiO and CuO-Co3O4 NCs using the microwave-assisted green method. Chapter 4, in sections 4.1 and 4.2 is devoted to the characterization and applications of 90:10, 80:20, and 70:30 CuO/Cu2O-ZnO, CuO/Cu2O-NiO, and CuO-Co3O4 NCs synthesized by microwave-assisted green method using Ipomoea carnea and Commelina benghalensis leaf extract. The % age scavenging potential of the synthesized materials was determined through serial dilution (800, 400, 200, 100, 50, and 25 and#956;g/mL) of the synthesized materials. newline newline newline newline
