Used as a precursor in the synthesis of rhenium-based catalysts for oxidation reactions. Employed in materials science for depositing silver and rhenium-containing thin films via chemical vapor deposition. Acts as a reagent in inorganic synthesis where both silver and perrhenate ions are needed. Shows potential in electrochemical applications due to the redox activity of the perrhenate anion. Also investigated for use in solid-state ionic conductors because of silver ion mobility in the crystal lattice.
