Role of "Dehalococcoides" spp. in the anaerobic transformation of Hexachlorobenzene in European rivers [PDF]

, 2011
The diffuse pollution by chlorinated organic compounds in river basins is a concern, due to their potential adverse effects on human health and the environment.

Dechlorination of Hexachloroethane in Water Using Iron Shavings and Amended Iron Shavings: Kinetics and Pathways

Journal of Chemistry, 2014
In contrast to previous studies which employed zero-valent iron powder, this paper investigated reductive dechlorination of hexachloroethane (HCA) using iron shavings and bimetallic iron shavings modified with Cu, Ag, or Pd.

Selective enrichment yields robust ethene-producing dechlorinating cultures from microcosms stalled at cis-dichloroethene. [PDF]

PLoS ONE, 2014
Dehalococcoides mccartyi strains are of particular importance for bioremediation due to their unique capability of transforming perchloroethene (PCE) and trichloroethene (TCE) to non-toxic ethene, through the intermediates cis-dichloroethene (cis-DCE ...

Inhibitory effects of metal ions on reductive dechlorination of polychlorinated biphenyls and perchloroethene in distinct organohalide-respiring bacteria

Environment International, 2020
Bioremediation of sites co-contaminated with organohalides and metal pollutants may have unsatisfactory performance, since metal ions can potentially inhibit organohalide respiration.

Mimicking reductive dehalogenases for efficient electrocatalytic water dechlorination

Nature Communications, 2023
Electrochemical technology is a robust approach to removing toxic and persistent chlorinated organic pollutants from water; however, it remains a challenge to design electrocatalysts with high activity and selectivity as elaborately as natural reductive ...

Acetylene Fuels TCE Reductive Dechlorination by Defined Dehalococcoides/Pelobacter Consortia. [PDF]

Environ Sci Technol, 2017
Acetylene (C2H2) can be generated in contaminated groundwater sites as a consequence of chemical degradation of trichloroethene (TCE) by in situ minerals, and C2H2 is known to inhibit bacterial dechlorination. In this study, we show that while high C2H2 (

Vacuum‐Induced Surface Reconstruction of Mn–Ce Oxides for Low‐Temperature Coupled Redox Catalysis

Angewandte Chemie, EarlyView.
Near‐surface reconstruction enhances low‐temperature redox catalysis in Mn–Ce mixed oxides. Sequential vacuum annealing and reduced‐pressure O2 treatment enrich Mn near the surface while preserving the CeO2 fluorite framework, promoting interfacial electron redistribution, oxygen activation, and redox cycling.

Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

Angewandte Chemie, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Agostic Hydridoborate Complexes as Masked Coinage‐Metal Hydrides: Hydride Migration Between Boron and Gold Unlocks CO2 Reactivity

Angewandte Chemie, EarlyView.
Hydride addition to coinage‐metal diphosphine–borane complexes gives unprecedented Cu(I), Ag(I), and Au(I) hydridoborates featuring agostic σ(B–H)→M interactions. While, Cu and Ag derivatives are inert toward CO2, the Au analogue reversibly fixes CO2 and catalyzes its hydroboration as well as formic acid dehydrogenation through a cooperative B─H─Au ...
