Anaerobic Dechlorinating Bacteria

Biotechnology Progress, 1998
AbstractAnaerobic dehalogenation is attracting great interest since it opens new research horizons based on the novel biochemical mechanisms identified in this field such as halorespiration, i.e. the utilization of halogenated compounds as electron acceptors.

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 ...

Bioelectrochemical Chlorinated Aliphatic Hydrocarbons Reduction in Synthetic and Real Contaminated Groundwaters

Chemical Engineering Transactions, 2022
The widespread contamination of chlorinated aliphatic hydrocarbons (CAHs) as Perchloroethylene (PCE) and Trichloroethylene (TCE) over the past recent years and their uncorrected disposal and storing brought these substances to become one of the most ...

Role of Graphene Oxide in the Nucleation and Growth of Gold Nanoparticles Revealed by Operando Time‐Resolved Studies

Angewandte Chemie, EarlyView.
Graphene oxide accelerates AuCl4− reduction under irradiation and directs edge‐selective nucleation and quasi‐one‐dimensional organization of gold nanoparticles at oxygen‐rich boundaries. Operando SAXS and UV–vis spectroscopy, supported by pulse radiolysis and DFT, reveal how progressive conversion of GO to rGO removes interfacial constraints, shifting

Reductive Dechlorination of 1,1,2,2-Tetrachloroethane [PDF]

Environmental Science & Technology, 2002
Products of the transformation of organic pollutants in the environment are often predicted based on the structure of the parent compounds. In some cases, however, multiple products may result from the same reaction pathway. In this study, the reduction of 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA) is investigated both experimentally and computationally.

Effects of humic electron mediators on reductive dechlorination of polychlorinated biphenyl by consortia enriched from terrestrial and marine environments

Frontiers in Microbiology
Humic electron mediators can facilitate the reductive dehalogenation of organohalogenated compounds by accelerating electron transfer. To investigate the effect of humic electron mediators on the microbial anaerobic reductive dechlorination of ...
