5-MERCAPTOTETRAZOLE-1-ACETIC ACID – STABILIZING AGENT FOR NOBLE METAL NANOPARTICLES IN WATER
Abstract
The novel stabilizing ligand, 5-mercaptotetrazole-1-acetic acid, has been applied for a simple synthesis of noble metal nanoparticles in the aqueous medium. This method is based on the reduction of metal salts in water in the presence of available 5-mercaptotetrazole-1-acetic acid. The interaction of the nanoparticle surface with the ligand has been investigated. According to quantum chemical calculations, the most stable structure has been realized when the capping ligand binds with the surface of nanoparticles through both sulphur and nitrogen N4 atoms. Free carboxyl groups provide good redissolvation in water.
Obtained particles are attractive as precursors for catalysts, as well as biologically active systems with antibacterial and fungicidal properties.
