Functionality of Metal Oxide-Based Core-Shell Nanoparticles

In recognition of their distinctive properties and diverse spectrum of applications in sectors such as catalytic processes, photocatalysis, biomedicine, biology, delivery of drugs, and sensing devices, core-shell nanostructures are currently attracting increased attention. The chemical composition and morphology of the core along with the shell of such nanomaterials can be transformed, leading to a wide range of tunable characteristics that may be essential in the development of catalyst and photocatalytic, and provide potential better and more efficient platforms for biomedical research. Due to their adjustable nanoscale functionality in both the core and shell parts, metallic materials such as Au, Ag, and Zn, along with metal oxide semiconductors such as ZnO, TiO₂, SiO₂, and SnO₂, have generated a lot of research attention in areas such as biomedicine, catalysis, and photocatalysis. In this chapter, the main focus was on some major synthesis techniques for the fabrication of core-shell nanostructures and various techniques employed for functionalizing the core, shell, or both in order to achieve improved and enhanced performance in different applications.
