Environmental context Contamination of shooting range soils by antimony (Sb) released
from corroding ammunition has become an issue of public environmental concern. Because …

Abstract Birnessite (δ-MnO 2) is the most common manganese (Mn) oxide mineral in soils,
sediments, and ocean manganese nodules, and it significantly affects the speciation and …

Manganese (Mn) oxides have high oxidation and sorption capacities, which enables them to
play important roles in antimony (Sb) migration and transformation. In this study, the …

The oxidation of arsenite (As (III)) by manganese oxide is an important reaction in both the
natural cycling of As and the development of remediation technology for lowering the …

Antimony (Sb) is a valuable mined commodity, used mostly in fire retardants, and
considered a critical element. It is also a potential environment hazard classed as a …

Antimony (Sb), which can be toxic at relatively low concentrations, may co-exist with Mn (II)
and/or Fe (II) in some groundwater and surface water bodies. Here we investigated the …

Recent studies of birnessite-type lattices show that they have an unusually low-lying band
structure with an electron affinity value of 6.0 eV, which is the highest among all common …

Because of their nanocrystallinity and high cation exchange capacities, birnessite phases
can control the cycling of heavy metals in soils and groundwaters, and they also are …

Synthetic hexagonal birnessite (Hx-birnessite) is a close analogue to natural poorly
crystalline phyllomanganate phases found in soils and marine ferromanganese deposits …

Although the oxidative capacity of manganese oxides has been widely investigated,
potential changes of the surface reactivity in dynamic anoxic/oxic environments have been …
