General description

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.

Application

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.

The direct growth of single-walled carbon nanotubes (SWCNTs) with narrow chiral distribution remains elusive despite substantial benefits in properties and applications. Nanoparticle catalysts are vital for SWCNT and more generally nanomaterial synthesis, but understanding their effect is limited. Solid catalysts
