Water Splitting and CO2 Reduction under Visible Light Irradiation Using Z-Scheme Systems Consisting of Metal Sulfides, CoOx-Loaded BiVO4, and a Reduced Graphene Oxide Electron Mediator.

Journal of the American Chemical Society, 2016
Metal sulfides are highly active photocatalysts for water reduction to form H2 under visible light irradiation, whereas they are unfavorable for water oxidation to form O2 because of severe self-photooxidation (i.e., photocorrosion).

Reductive Sulfidation. Conversion of Aldehydes into Sulfides

Synthetic Communications, 1976
Abstract Carbonyl compounds have been converted into 1,3-oxathiolanes or 1,3-oxathianes and then reduced with “mixed hydride” to β-hydroxyethyl (or on further reduction ethyl) or γ-hydroxypropyl sulfides, respectively.1 However, this overall conversion of a carbonyl compound to a sulfide (a process for which the name reductive sulfidation is suggested ...

Adaptations to sulfide in the meiofauna of the sulfide system. I. 35S-sulfide accumulation and the presence of a sulfide detoxification system

Journal of Experimental Marine Biology and Ecology, 1979
Abstract Life in the sulfide system requires the ability to withstand the toxic effects of long-term sulfide stress. The adaptations of sulfide-system interstitial metazoans to sulfide stress have been investigated using 35 S-sulfide. One possible adaptation, the total exclusion of sulfide at the body wall, could not be demonstrated.

On the volumetric determination of hydrogen sulfide and soluble sulfides

Analytica Chimica Acta, 1953
Abstract I. Common sources of eiior in the lodumetric methods fur the determination ol hydiogen sultide and soluble sulfides are discussed. An improved method for the lodometric dctermination is described and its precision and accuracy are discussed. II. The volumetric determination of sulfides by means of alkaline hypochlorite solutions is discussed.
