Silver-Exchanged Zeolites: Preparation and Applications-A Review.

Zeolites are widely acknowledged as minerals with outstanding characteristics, primarily due to their complex porous structure and large specific surface area. The modification of natural and synthetic zeolites can improve their properties, making them suitable for a wider range of applications. In recent years, silver-exchanged natural zeolites have been increasingly studied because silver is known for its antimicrobial and electrical conductivity properties, which enhance their utility in various fields. This study aims to provide a comprehensive review specifically focused on the silver-zeolite composite system. It synthesizes advancements in silver modified zeolites, offering a targeted analysis that connects synthesis methodologies to enhanced properties and applications. The paper is structured to include an overview of the general characteristics of both natural and synthetic zeolites, and methods for their modification to serve as supports for Ag+ and silver nanoparticles (AgNPs). It subsequently covers the properties of silver-exchanged zeolites and their principal applications. The study also summarizes the advantages and limitations of these materials, along with an analysis of future trends regarding new production possibilities and potential applications.
