Emerging Trends and Future Perspectives of Functionalized Layered Double Hydroxides

Abstract

The physiochemical features of two-dimensional layered double hydroxides (LDHs) have generated considerable interest. LDHs have the potential to be valuable in several applications, especially in the disciplines of environmental science, energy production, catalysis, and biomaterials. Although LDHs possess distinctive inherent characteristics, they have been subjected to several methods of functionalization that result in even more remarkable performance possibilities. These procedures provide valuable insights for the preparation of innovative functional nanomaterials. This chapter focuses on the ways in which these tactics might enhance the different characteristics of LDHs. We present a comprehensive analysis of the methods used to enhance the functionality of materials, including intercalation, surface modification, hybridization, management of layered compositions, control of size and morphology, and generation of defects. These techniques play a vital role in improving the performance of LDHs in several fields, including adsorption, catalysis, electronics, electrochemistry, and optics. Functionalized LDHs have significant promise for many environmental and energy applications. We have extensively emphasized their growing promise in various fields, including the removal of heavy metals, capture of radionuclides, purification of organic contaminants, elimination of oil pollution, generation of hydrogen, fabrication of biomaterials and in the development of supercapacitors, batteries, solar cells and catalysts.
