This review summarizes recent applications of copper or copper-based compounds as a nonprecious metal catalyst in N-nucleophiles-based dehalogenation (DH) reactions halogenated aromatic (Ar-Xs). Cu-catalyzed DH enables the production corresponding nonhalogenated products (Ar-Nu), which are much more biodegradable and can be mineralized during aerobic wastewater treatment principally further app...

The effect of copper and its compounds on halogenation dehalogenation aromatic will be discussed in the proposed article. Cu oxidized to appropriate halides is an effective catalyst not only for synthesis halogenated benzenes or their derivatives as desired organic fine chemicals, but also undesirable formation thermodynamically stable very toxic polychlorinated polybrominated such biphenyls, d...

Title of Document: CATALYTIC FEATURES OF THE IODINE SALVAGING ENZYME IODOTYROSINE DEIODINASE. Patrick Michael McTamney, II Doctor of Philosophy, 2009 Directed By: Professor Steven Rokita Department of Chemistry and Biochemistry The need for iodide in biology is almost exclusively limited to its role in thyroid hormones, yet the recycling of thyroidal iodide is still critical for human health. T...

UNLABELLED Chloroflexi small-subunit (SSU) rRNA gene sequences are frequently recovered from subseafloor environments, but the metabolic potential of the phylum is poorly understood. The phylum Chloroflexi is represented by isolates with diverse metabolic strategies, including anoxic phototrophy, fermentation, and reductive dehalogenation; therefore, function cannot be attributed to these organ...

Biofiltration of air polluted by volatile organic compounds is now recognized by the industrial and research communities as an effective and viable alternative to standard environmental technologies. Whereas many studies have focused on solid/liquid/gas biofilters, there have been fewer reports on waste air treatment using other biological processes, especially in a solid/gas biofilter. In this...

Pseudomonas putida PP3 grew on DL-2-monochloropropionate (2MCPA) with a release of chloride ions consistent with the dechlorination of both isomers. The organism grew on either D- or L-2MCPA. Dehalogenase activity in cell-free extracts showed that both D- and L-2MCPA were dehalogenated. Pseudomonas putida PP3 contains two dehalogenases, and studies with the separated enzymes revealed that the f...

We report a synthetic approach to form cubic Cu2O/Pd composite structures and demonstrate their use as photocatalytic materials for tandem catalysis. Pd nanoparticles were deposited onto Cu2O cubes, and their tandem catalytic reactivity was studied via the reductive dehalogenation of polychlorinated biphenyls. The Pd content of the materials was gradually increased to examine its influence on p...
