Towards excellent electrical conductivity and high-rate capability: A degenerate superlattice Ni3(S)1.1(S2)0.9 micropyramids electrode

Degenerate semiconductor is very highly desired in energy conversion and storage technologies due to its metal-like conduction behaviors. This is the first time the doping S2 in Ni3S2 lattice into chemically homogeneous Ni3(S)1.1(S2)0.9 superlattice structure is proposed to induce a degenerate characteristic towards excellent electrical conductivity and high-rate capability. In this study, a series of the chemically homogeneous S2-doped Ni3(S)1.8(S2)0.2, Ni3(S)1.6(S2)0.4, Ni3(S)1.3(S2)0.7, and Ni3(S)1.1(S2)0.9 micropyramid arrays on Ni foam were synthesized by reacting the Ni foam and alkaline sulfur aqueous solution in different S22- concentrations. The perfect Ni3(S)1.1(S2)0.9 superlattice structure corresponds to the periodic S–Ni–S2 atom arrangements in whole crystal lattice, which endows a degenerate characteristic of metal-like electrical conductivity to significantly improve the electrochemical performance. The bulk series resistance (Rs) value is only 0.62 Ω, while the charge-transfer resistance (Rct) is nearly 0 Ω in the superlattice Ni3(S)1.1(S2)0.9 electrode. As a cathode material for application in lithium ion batteries (LIBs), a very high specific capacity of 874 mAh g?1 is achieved at current density of 200 mA g?1. Remarkably, it still holds a high capacity of 565 mAh g?1 at current density of 500 mA g?1, indicating its superior high-rate capability. This study reveals that the periodic S–Ni–S2 atom arrangements in crystal lattice is a key factor in determining the superlattice structure, high specific capacity, and the dynamic behaviors of electron/ion transport.

Electrochemical synthesis of organochalcogenides in aqueous medium

The electrochemical preparation of telluride, selenide and sulfide ions was carried out in NaOH aqueous solution, using a two compartment cell. Organochalcogenides were prepared from halogenated compounds in a two-step procedure. The monochalcogenides were obtained as the major products in good yields.

General Model for the Nonlinear pH Dynamics in the Oxidation of Sulfur(-II) Species

A general kinetic feature has been observed experimentally for the oxidation of the sulfur(-II) species thiosulfate, thiourea, thiocyanate, and sulfide by chlorite and other multi-equivalent oxidants under appropriate, unbuffered batch conditions. This fingerprint consists of an initial rise in pH followed by an autocatalytic drop in pH or oligo-oscillatory behavior. These systems also exhibit oscillations and other complex dynamical behavior in a continuous-flow stirred tank reactor (CSTR). The previously proposed general models that are oxidant based do not successfully explain the observed pH effects. We propose a simple, general model that is based upon the changing oxidation states of sulfur to explain the general pH features. The scheme qualitatively models autocatalysis and oligo-oscillations in batch and simple and complex oscillations in a CSTR. The general model consists of three separate stages: negative hydrogen ion feedback (S(-II) to S(0)), a transition of S(0) to S(IV), and positive proton feedback from S(IV) to S(VI).

Chemical species in sulfur-ammonia solutions: Influence of amide addition

The acidity of sulfur-ammonia solutions has been modified by the introduction of an alkali-metal amide, and the chemical composition of the solution has been studied by using UV-visible spectrophotometry and Raman spectroscopy. It is shown that the progressive introduction of an alkali-metal amide makes the oxidized species more oxidized and the reduced species more reduced. It is found that, in sulfur-ammonia solutions, a chemical species less oxidized than S4N- exists in solution, which is neither S7N- nor a polysulfide; it is suggested that this species is a neutral form of sulfur. It is shown that the concentration of S4N- can be increased after amide addition by a factor of about 3 for a 10-2 M solution. Other oxidized forms of sulfur that have been observed are assigned to S3N- and S2N-. Very slow kinetics are observed for the modifications of the species induced by the introduction of the alkali-metal amide.

Electrochemical studies of sulfur-nitrogen compounds. 2. The S4N- and S3N- ions, S7NH, 1,4-S6(NH)2, S4N4H4, and 1,3-S4N2

The electrochemical reduction of the S4N- and S3N- ions, S7NH, 1,4-S6(NH)2, S4N4H4, and 1,3-S4N2 on mercury and platinum electrodes in acetonitrile containing 0.1 M M+ClO4- (M+ = Li+, Na+, or R4N+ where R = Me, Et, or n-Bu) has been investigated, and the identity of the products was determined by polarography and UV-visible spectroscopy. The reduction of the S4N- ion (λmax 580 nm) on a mercury-pool electrode in acetonitrile-0.1 M Et4N+ClO4- at -1.8 V (vs. Ag/0.1 M AgClO4-MeCN) produced S3N- (λmax 465 nm) and consumed more than 1 e/mol. Further reduction of the S3N- ion at -2.2 V produced a new binary sulfur-nitrogen anion (λmax 375 nm) tentatively assigned as the S2N- ion. A similar sequence of reductions occurred at the platinum electrode. The electrochemical reduction of S7NH at -1.45 V on a mercury pool resulted in the uptake of 1 e and the formation of S4N-, S3N-, and HgS, while at a platinum electrode at -1.75 V the products were the 375-nm species and S3-·, in addition to S4N- and S3N-, and the n value was 4. The behavior of 1,4-S6(NH)2 on electrochemical reduction was similar to that of S7NH except that no S3-· was formed and the ratio S3N-:S4N- was greater for 1,4-S6(NH)2. The exhaustive electrolysis of S4N4H4 at -2.8 V in acetonitrile-0.05 M Me4NClO4 gave an n value of ca. 8 and produced the SN22- ion. The reduction of 1,3-S4N2 at -1.2 V on a mercury pool produced only S3N3- and HgS and an n value of ca. 0.7, while electrolysis at a platinum electrode at -1.4 V gave both S4N- and S3N3- and an n value slightly greater than unity.

Molten lithium sulfate-sodium sulfate-potassium sulfate eutectic: Reactions of some sulfur compounds

The reactions of sulfide and of five sulfur oxyanion salts (Na2SO3, Na2S2O5, K2S2O5, Na2S2O3, and K2S2O7) were studied by themselves and in the molten ternary sulfate eutectic under nitrogen, with air, sulfur dioxide, sulfur trioxide, and carbon dioxide, and with acidic, basic, and reducing solutes. The sulfur-containing products were elemental sulfur and sulfate though sulfur oxides were sometimes evolved and a number of intermediates formed. Reaction products were identified qualitatively and quantitatively, often by TGA, and reaction schemes are suggested.
