Molten salt-assisted one-pot synthesis of Ag nanoparticles supported on clay minerals for enhanced antibacterial performance.

ABSTRACT: Supported silver nanoparticles (AgNPs) have been extensively used as antibacterial agents in biomedicine, biotechnology, and environmental remediation. However, a facile and scalable method for preparing homogeneously dispersed AgNPs on clay minerals remains a challenge. In this study, a one-pot method was successfully developed for the synthesis of homogeneously dispersed AgNPs supported on the surface of clay minerals (e.g., montmorillonite (Mt) and palygorskite (Pal)). Typically, clay minerals were mixed with AgNO₃ (as a precursor) and NaNO₃ (as a dispersant) by thorough grinding in a mortar, and then the mixture was heated slowly. AgNO₃ undergoes thermal decomposition to generate AgNPs via a self-reduction process, without the assistance of any external reductants
