Anion-exchange phase control of manganese sulfide for oxygen evolution
Manganese sulfide usually exists as MnS 2 (cubic), β-MnS (zinc blende), γ-MnS (wurtzite), and α-MnS (rock salt) polymorphs. In this study, polymorphic thin films of MnS 2, γ-MnS, and α-MnS were prepared from manganese carbonate through anion exchange and controlled reaction kinetics via a hydrothermal method. At the same mass ratio (1 : 1) of …

Amorphous cobalt-manganese sulfide electrode for efficient water
These microstructures are found to be quite similar to previous reports for cobalt sulfide and manganese sulfide deposited by wet-chemical methods [49], [50], [51]. As a small amount of manganese is added at the expense of cobalt ((Co 4 Mn 1)S), the microstructure becomes slightly porous and exhibits a partial sheet-like morphology (Fig. …

3.4: Molecular and Ionic Compounds
Ionic and molecular compounds are named using somewhat-different methods. Binary ionic compounds typically consist of a metal and a nonmetal. The name of the metal is written first, followed by the name of the nonmetal with its ending changed to – ide. For example, K 2 O is called potassium oxide.
Manganese (Sedimentary Carbonates and Sulfides)
Manganese sulfide formation in anoxic sediments. The only places worldwide where sedimentary manganese sulfides have been found sofar are the Baltic Sea anoxic deeps (e.g., Baron and Debyser, 1957 ). Idiomorphic MnS (Figure 2) is associated with organic matter, Ca-rhodochrosite, and iron sulfides (Böttcher and Huckriede, 1997; Lepland and ...
