“…12,13 The nature of the 'much argued over' species, monoatomic rhenide (Re − ), in aqueous solution is still unknown, nevertheless, is accepted certainly not as a simple anion but rather a type of hydride or oxygenated complex. 14,15 Experimentally, in a non-acidic system, an exchange of oxygen between the ReO 4 − and H 2 O occurs with a calculated activation energy of 64.85 kJ mol −1 , 16 diminishing the formation of perrhenic acid (HReO 4 ). The solvent-assisted oxygen dissociation path for the Re − O bond in a non-catalyzed path in a water system is shown in Fig.…”

This review addresses the dearth of knowledge about the interaction of rhenium species with organic solvents during the liquid–liquid extraction of rhenium. To describe such interactions, the aqueous chemistry of rhenium in unlike media, the extraction mechanism and the salient role of thermodynamic properties are also discussed. Formation of a rhenium‐complexed species inorganic phase and competition between the extracted species during extraction is described by inner and outer sphere coordination. Emergence of a stabilized complex in a hydrophobic environment is greatly affected by the interaction of electrostatic and/or H‐bonding. The chemistry of liquid–liquid extraction of rhenium that can further assist future studies in this area is also relevant to other metal ion systems. © 2015 Society of Chemical Industry

“…In addition, ReS 2 is a stable layered material with a distorted tetragonal (DT) structure and has the same chemical stoichiometry as MoS 2 . Moreover, Re metal is also active for HER . Thus, we expected that alloys of (Re,Mo)S 2 would form a stable T‐phase structure with high HER performance.…”

Rhenium‐Doped and Stabilized MoS₂ Atomic Layers with Basal‐Plane Catalytic Activity

The development of stable and efficient hydrogen evolution reaction (HER) catalysts is essential for the production of hydrogen as a clean energy resource. A combination of experiment and theory demonstrates that the normally inert basal planes of 2D layers of MoS2 can be made highly catalytically active for the HER when alloyed with rhenium (Re). The presence of Re at the ≈50% level converts the material to a stable distorted tetragonal (DT) structure that shows enhanced HER activity as compared to most of the MoS2‐based catalysts reported in the literature. More importantly, this new alloy catalyst shows much better stability over time and cycling than lithiated 1T‐MoS2. Density functional theory calculations find that the role of Re is only to stabilize the DT structure, while catalysis occurs primarily in local Mo‐rich DT configurations, where the HER catalytic activity is very close to that in Pt. The study provides a new strategy to improve the overall HER performance of MoS2‐based materials via chemical doping.

“…Rhenium has also been applied for ammonia synthesis and hydro‐denitrogenation, and it is a potential photo‐electrocatalyst for reduction of nitrate ions . Rhenium has been suggested for hydrogen evolution reaction (HER) as well but with contradictory results . Notably, Re should perform similarly as Co and Ni in HER, but rhenium oxides are even better and as good as Pt, which is considered to be the most effective HER catalyst.…”

Rhenium Metal and Rhenium Nitride Thin Films Grown by Atomic Layer Deposition

Rhenium is both a refractory metal and a noble metal that has attractive properties for various applications. Still, synthesis and applications of rhenium thin films have been limited. We introduce herein the growth of both rhenium metal and rhenium nitride thin films by the technologically important atomic layer deposition (ALD) method over a wide deposition temperature range using fast, simple, and robust surface reactions between rhenium pentachloride and ammonia. Films are grown and characterized for compositions, surface morphologies and roughnesses, crystallinities, and resistivities. Conductive rhenium subnitride films of tunable composition are obtained at deposition temperatures between 275 and 375 °C, whereas pure rhenium metal films grow at 400 °C and above. Even a just 3 nm thick rhenium film is continuous and has a low resistivity of about 90 μΩ cm showing potential for applications for which also other noble metals and refractory metals have been considered.
