“…Layer ReX 2 (X = S, Se) are of considerable interest for various applications due to their optical, electrical and mechanical properties. These applications include a sulfur-tolerant hydrogenation and hydrodesulfurization catalyst [3,4] and as a promising solar-cell material in electrochemical cells [5,6]. Unlike most of the layered TMDCs, ReX 2 crystallizes in a distorted CdCl 2 -type layer structure with triclinic symmetry.…”

“…The cluster bromide of niobium and chlorides of molybdenum, tantalum, and tungsten also showed catalytic activity for the isomerization of olefin. Although rhenium metal [58] and rhenium sulfides [59] have been reported to be hydrogenation catalysts, a rhenium cluster, Re 3 Cl 9 , had no catalytic activity under the same reaction conditions. The catalytic activity varied with the cluster catalyst employed; however, the cis/trans selectivities of 2-hexene remained in a relatively narrow range and the ratios are approximately in accord with that of thermal equilibrium (0.77 at 250 °C).…”

Halide clusters of Group 5-7 metals develop catalytic activity above 150-250 °C, and the activity is retained up to 350-450 °C by taking advantage of their thermal stability, low vapor pressure, and high melting point. Two types of active site function: the solid Brønsted acid site and a coordinatively unsaturated site that catalyzes like the platinum metals do. Various types of catalytic reactions including new reactions and concerted catalyses have been observed over the clusters: hydrogenation, dehydrogenation, hydrogenolysis, isomerization of alkene and alkyne, and alkylation of toluene, amine, phenol, and thiol. Ring-closure reactions to afford quinoline, benzofuran, indene, and heterocyclic common rings are also catalyzed. Beckmann rearrangement, S-acylation of thiol, and dehydrohalogenation are also catalyzed. Although the majority of the reactions proceed over conventional catalysts, closer inspection shows some conspicuous features, particularly in terms of selectivity. Halide cluster catalysts are characterized by some aspects: cluster counter anion is too large to abstract counter cation from the protonated reactants, cluster catalyst is not poisoned by halogen and sulfur atoms. Among others, cluster catalysts are stable at high temperatures up to 350-450 °C. At high temperatures, apparent activation energy decreases, and hence weak acid can be a catalyst without decomposing reactants. OPEN ACCESSMetals 2014, 4 236

“…3) Owing to their unique optical, electrical, and mechanical properties, the layered-type compounds have attracted much attention in basic studies and applications. They can be used as a sulfur-tolerant hydrogenation, hydrodesulfurization catalyst, 4,5) a promising solar-cell material in electrochemical cells, 6,7) and a material for the fabrication of polarization-sensitive photodetectors in the visible wavelength region. 8) The optical anisotropy of ReS 2 with polarization along and perpendicular to the b-axis have been reported using polarization-dependent absorption, 9,10) piezoreflectance (PzR), and thermoreflectance (TR) experiments.…”

In this article, we present the optical study of undoped and Au-doped rhenium disulphide (ReS 2 and ReS 2 :Au) using temperature-and polarization-dependent thermoreflectance (PTR) and reflectance (R) measurements. We have observed the indirect band gaps (E gk , E g? ), and direct band-edge excitonic transitions (E ex 1 , E ex 2 , E ex 3 and E ex 4 ) at various polarization angles. The amplitudes of E ex 1 and E ex 2 transitions have an orthogonal characteristic and follow the Malus rule. A small blue-shift of indirect band gaps has been observed for the ReS 2 :Au sample, we believe that this result is contributed from the doping effects. We also measured the temperature-dependent PTR spectra in the temperature range from 55 to 300 K, and determined the temperature dependences of the transition energies and broadening parameters of E ex 1 and E ex 2 transitions. Reflectance measurements at various polarizations have been performed to confirm our observations.
