Book excerpt: Non-renewable energy resources are becoming depleted, and storing solar energy in the chemical bonds of molecules is an attractive alternative. The splitting of water into hydrogen and oxygen is one potentially viable option; however, many mechanistic details remain unknown. Motivated by the known similar oxidation of hydrogen sulfide (H2S) in hydrothermal vents, this study investigates the oxidation mechanisms in mixed hydrogen sulfide/water model complexes. Quantum structures, properties, spectroscopic signatures, and relative energies are presented for the oxidized hydrogen sulfide dimer, [(H2S)(H2S)]+, and the mixed dimer, [(H2S)(H20)]+, using computational quantum chemistry techniques. High-level coupled-cluster approaches are used to provide benchmark references and appropriate density fiinctionals for faster simulations. The mixed dimer is found to exhibit traits intermediate to the limiting regimes of oxidized water (a proton-transferred, ion-radical complex, H3O+ ••• OH) and oxidized hydrogen sulfide (a hemi-bonded complex, (H2S)+2). These results provide fundamental properties which begin to depict the environment and unique chemistry surrounding hydrothermal vents.

Available in PDF, EPUB and Kindle. Book excerpt: Sulfur compounds contaminate many industrially important feedstocks and, on release to the atmosphere as sulfur oxides, can cause widespread damage to the ecosystem. The main objectives of The Sulfur Problem: Cleaning Up Industrial Feedstocks are to demonstrate the importance of eliminating sulfur contaminants from the environment and the measures necessary to effect this. Using a systematic and pedagogical approach, the reader is first presented with the problem. Current technology for solving it is then outlined together with appropriate theory on the synthesis, structure and sorption behaviour of the materials used. Relevant characterisation techniques are described with reference to typical sorbents, to demonstrate how the sorption behaviour of the materials correlates with their properties. The book is unique in blending together aspects of environmental chemistry, materials/solid state chemistry, surface chemistry, catalysis and separation processes to address the problem of sulfur contaminants in a wide range of feedstocks.

Available in PDF, EPUB and Kindle. Book excerpt: Commonly, abatement of hydrogen sulfide emissions from a geothermal powerplant requires that hydrogen sulfide dissolved in the cooling water be eliminated by chemical reaction. Oxidation by atmospheric oxygen is the preferred reaction, but requires a suitable catalyst. Nickel is the most potent and thereby cheapest catalyst for this purpose. One Mg/L nickel in the cooling water would allow 99% removal of hydrogen sulfide to be attained. A major drawback of catalytic air oxidation is that colloidal sulfur is a major reaction product; this causes rapid sludge accumulation and deposition of sulfur scale. The authors studied the kinetics and product distribution of the reaction of hydrogen sulfide with oxygen, catalyzed by nickel. Adding sodium sulfite to the solution completely suppresses formation of colloidal sulfur by converting it to thiosulfate. The oxidation reaction is an autocatalytic, free radical chain reaction. A rate expression for this reaction and a detailed reaction mechanism were developed. Nickel catalyzes the chain initiation step, and polysulfidoradical ions propagate the chains. Several complexes of iron and cobalt were also studied. Iron citrate and iron N-hydroxyEDT are the most effective iron based catalysts. Uncomplexed cobalt is as effective as nickel, but forms a precipitate of cobalt oxysulfide and is too expensive for practical use.
