Enhanced catalytic hydrodechlorination of 2,4-dichlorophenoxyacetic acid by nanoscale zero valent iron with electrochemical technique using a palladium/nickel foam electrode.

Highlights: [•] Enhanced catalytic dechlorination of 2,4-dichlorophenoxyacetic acid. [•] Synergistic technology combined nZVI with electrochemistry. [•] Palladium loading and current density had a greater impact on efficiencies. [•] nZVI promoted the generation of electron and enhanced the dechlorination. [Copyright &y& Elsevier]
