Dehalogenation of environmental pollutants in microbial electrolysis cells with biogenic palladium nanoparticles

Purpose of work Hydrodehalogenation of persistent pollutants, such as the groundwater contaminants trichloroethylene and diatrizoate, are catalyzed by biogenic Pd nanoparticles. As H2 gas supply for the dehalogenation reactions is still the limiting factor, this study examines in situ H2 production in the cathode of a microbial electrolysis cell.
