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 electronic, optical and chemical properties of two-dimensional transition metal dichalcogenides strongly depend on their three-dimensional atomic structure and crystal defects. Using Re-doped MoS2 as a model system, here we present scanning atomic electron tomography as a method to determine

Tuning bandgap and phases in the ternary 2D transition metal dichalcogenides (TMDs) alloys has opened up unexpected opportunities to engineer optoelectronic properties and explore potential applications. In this work, a salt-assisted chemical deposition vapor (CVD) growth strategy is reported for
