“…Interestingly, the MoS x chalcogel does not consist of a random arrangement of interconnected ligands. 25 Gas Adsorption and Selectivity. The porous nature and high polarizable internal pore surface of the MoS x chalcogel prompted us to investigate the adsorption properties with H 2 , CO 2 , CH 4 and C 2 H 6 .…”

We report the synthesis of ion-exchangeable molybdenum sulfide chalcogel through an oxidative coupling process, using (NH4)2MoS4 and iodine. After supercritical drying, the MoS(x) amorphous aerogel shows a large surface area up to 370 m(2)/g with a broad range of pore sizes. X-ray photoelectron spectroscopic and pair distribution function analyses reveal that Mo(6+) species undergo reduction during network assembly to produce Mo(4+)-containing species where the chalcogel network consists of [Mo3S13] building blocks comprising triangular Mo metal clusters and S2(2-) units. The optical band gap of the brown-black chalcogel is ∼1.36 eV. The ammonium sites present in the molybdenum sulfide chalcogel network are ion-exchangeable with K(+) and Cs(+) ions. The molybdenum sulfide aerogel exhibits high adsorption selectivities for CO2 and C2H6 over H2 and CH4. The aerogel also possesses high affinity for iodine and mercury.

Oxidation Leading to Reduction: Redox‐Induced Electron Transfer (RIET)

2008

View full text Add to dashboard Cite

Complex electron transfer reactions have been characterized whereby in addition to electron transfer, subsequent electrochemical, chemical and even in some cases biological consequences occur. These include a secondary electron transfer that leads to a major rearrangement of the electronic structure, such that an initial oxidation leads to a reduction (or an initial reduction leads to an oxidation) for these valence ambiguous compounds. Mixed valency and valence-tautomeric behaviors can additionally result from these complex electron-transfer-induced reactions.

“…Motivation for this research includes the search for new materials with interesting properties(i,2). In particular, mixed-metal Cu--Mo(W)--S clusters have attracted attention because of their relevance to biological systems (3'4), in catalytic processes (5) and nonlinear optical materials (6)(7)(8). Not only Cu--Mo(W)--S clusters, but also Ag--Mo(W)--S compounds have been systematically studied ~176 Over 160 Cu(Ag)--Mo(W)--S compounds have been reported (11).…”

structure of a novel cluster, SummaryThe cluster [WS4Ag3I(AsPh3)3](SAsPh3) was prepared by the solid state reaction of (NH4)2WS~, AgI and AsPh 3 at low heat. Some AS nI atoms were oxidized to As v in the process. The structure of [WS4Ag3I(AsPh3)3](SAsPh3) was determined by single crystal X-ray diffractometry and can be described as the combination of cubane-like [WS4Ag3I(AsPh3)3] with an SAsPh 3 moiety.
