Combined use of ISCR and biostimulation techniques in incomplete processes of reductive dehalogenation of chlorinated solvents [PDF]

, 2020
Pools of chloroethenes are more recalcitrant in the transition zone between aquifers and basal aquitards than those elsewhere in the aquifer. Although biodegradation of chloroethenes occur in this zone, it is a slow process and a remediation strategy is ...

Palladium/iron nanoparticles stimulate tetrabromobisphenol a microbial reductive debromination and further mineralization in sediment

Environment International, 2020
Tetrabromobisphenol A (TBBPA) has aroused serious pollution in surface sediment. To date, whether and how iron-based nanoparticles could stimulate TBBPA in situ anaerobic biodegradation in sediment remains poorly understood. In this study, the distinctly

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

Angewandte Chemie International Edition, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Ultrafine Zinc and Nickel, Palladium, Silver Coated Zinc Particles Used for Reductive Dehalogenation of Chlorinated Ethylenes in Aqueous Solution [PDF]

, 1998
Zero-valent zinc metal has been employed for the reductive dehalogenation of chlorinated ethylenes. In order to enhance this environmental remediation chemistry, ultrafine zinc particles and transition metal additives (coatings) have been employed ...

Evidence of microbial reductive dehalogenation in deep-sea cold seeps and its implications for biogeochemical cycles

Microbiome
Background Reductive dehalogenation is crucial for halogen cycling and environmental remediation, yet its ecological role is not completely understood, especially in deep-sea environments. To address this gap, we investigated the diversity and expression

Genome-resolved transcriptomics reveals novel PCE-dehalogenating bacteria from Aarhus Bay sediments

mSystems
Organohalide-respiring bacteria (OHRB) are keystone microbes in bioremediation of sites contaminated with organohalides and in natural halogen cycling.

Remediation of Polychlorinated Biphenyls (PCBs) in Contaminated Soils and Sediment: State of Knowledge and Perspectives

Frontiers in Environmental Science, 2018
Polychlorinated biphenyls (PCBs) are one of the persistent organic pollutants (POPs) used worldwide between the 1930 and 1980s. Many PCBs can still be found in the environment such as in soils and sediments, even though their use has been heavily ...

On‐Surface Friedel–Crafts Alkylation Through a Stabilized Intermediate Complex

Angewandte Chemie International Edition, EarlyView.
On‐surface Friedel–Crafts alkylation is demonstrated on Ag(111) at the single‐molecule level. STM, XPS, and DFT calculations uncover the reaction mechanism and explain the stabilization of the key intermediate, providing insight into noble‐metal‐surface‐mediated Csp3${\rm C}_{sp^{3}}$─Csp2${\rm C}_{sp^{2}}$ coupling. ABSTRACT The incorporation of sp3${\

CdS-Based Hydrothermal Photocatalysts for Complete Reductive Dehalogenation of a Chlorinated Propionic Acid in Water by Visible Light

Nanomaterials
Cadmium sulfide (CdS)-based photocatalysts are prepared following a hydrothermal procedure (with CdCl2 and thiourea as precursors). The HydroThermal material annealed (CdS-HTa) is crystalline with a band gap of 2.31 eV. Photoelectrochemical investigation
