Descrizione generale

Ammonium perrhenate is a white crystalline solid soluble in ethanol and water. It is a weak oxidizer and widely used as a Re precursor in nanomaterial synthesis and Re-based catalyst preparation.

Applicazioni

Ammonium perrhenate used:
  • As a rhenium source to prepare Re nanoparticles for catalytic decomposition of ammonium perchlorate.
  • To synthesize ReS2 through a direct sulfidation reaction, for the fabrication of field effect transistors (FETs), digital logic devices, humidity sensors, and rechargeable supercapacitors.
  • As a precursor to prepare the heterogeneous catalysts for organic transformations.
  • An excellent precursor for the fabrication of ReOx/TiO2 recyclable solidcatalyst for deoxydehydration. For at least six runs in a row, the catalyst demonstrated catalyticactivity, selectivity, and stability without deactivation.
