Green synthesis and applications of ceria-based nanomaterials

Abstract

In recent years, there has been a growing interest in developing environmentally and sustainable methods for the synthesis of nanomaterials (NMs). Among various NMs, ceria-based NMs have gained significant attention due to their unique properties and diverse applications. This chapter provides a comprehensive overview of the green synthesis approaches employed for the fabrication of ceria-based NMs and their subsequent applications. The chapter begins with an introduction to ceria-based NMs, highlighting their exceptional physicochemical properties such as high surface area, redox capabilities, and oxygen storage capacity. Subsequently, it delves into the concept of green synthesis, emphasizing the significance of using environmentally benign routes for NMs fabrication. Various green synthesis methods, including biological, template-mediated, and microwave-assisted techniques, are discussed in detail, highlighting their advantages, limitations, and applicability to ceria-based NMs. Furthermore, the chapter explores the wide-ranging applications of ceria-based NMs in different fields, such as catalysis, energy storage and conversion, environmental remediation, and biomedical applications. Specific examples and case studies are presented to illustrate the effectiveness of ceria-based NMs in these applications. Additionally, the chapter discusses the potential challenges and future perspectives associated with the green synthesis and applications of ceria-based NMs, including scalability, stability, and toxicity considerations. By adopting sustainable and environmentally friendly approaches, the synthesis and applications of ceria-based NMs can contribute to the development of cleaner and more efficient technologies for a sustainable future.
