PHOTOCATALYTIC ACTIVITIES OF ZnO DOPED BIOPOLYMER NANOCOMPOSITE

In recent years, the field of nanotechnology has seen remarkable advancements, particularly in the realm of nanocomposites, where two or more distinct materials are combined at the nanoscale to achieve unique properties. Among these, zinc oxide (ZnO) doped biopolymer nanocomposites have emerged as a promising class of materials with diverse applications spanning electronics, optoelectronics, sensors, energy storage, and biomedical engineering. ZnO, a wide-bandgap semiconductor with excellent optical, electrical, and piezoelectric properties, serves as an attractive matrix material for nanocomposite fabrication. The introduction of nanocomposite offers additional functionalities, such as enhanced mechanical flexibility, improved processability, and tunable electrical and optical properties. The resulting zinc oxide (ZnO) doped biopolymer nanocomposites exhibit synergistic effects derived from the combination of the unique characteristics of both components. This preface sets the stage for exploring the synthesis, characterization, properties, and applications of zinc oxide (ZnO) doped biopolymer nanocomposites. Through interdisciplinary research efforts at the intersection of materials science, chemistry, physics, and engineering, these nanocomposites hold immense potential for addressing various technological challenges and fostering innovation in diverse fields. This book aims to provide a comprehensive overview of the state-of-the-art developments in this exciting area of nanotechnology, offering insights into fundamental principles, techniques, performance optimization strategies, and emerging applications of zinc oxide (ZnO) doped biopolymer nanocomposites.

Zinc oxide (ZnO) nanocomposites exhibit significant photocatalytic activity due to their unique properties, including a wide bandgap (approximately 3.3 eV), high surface area, and excellent electron-hole pair generation efficiency. When ZnO is combined with other materials to form nanocomposites, the synergistic effects can enhance its photocatalytic performance in various ways. Here we are using zinc oxide doped biopolymer nanocomposites and their enhanced photocatalytic activities. Overall, ZnO nanocomposites offer promising opportunities for the development of efficient photocatalytic materials with enhanced performance and versatility for various environmental and energy-related applications.
