Electrochemical reductive dechlorination of trichloroacetic acid on porous Ag-Pd thin foam

Porous Ag-Pd thin foam (PAPTF) possesses high electrocatalytic activities towards reductive dechlorination of trichloroacetic acid in alkaline media and is expected to be promising electro catalyst for the dechlorination of chlorinated organic wastes. The electrocatalytic activities of PAPTF depend mainly on the Ag components and the morphology. However, the content of Pd(II) in the system can strongly affect the electrocatalytic performance. In this work, PAPTF was fabricated through a rapid one-step electrodeposition method within the hydrogen bubble dynamic template and characterized by SEM, EDS, and cyclic voltammetry. Morphology and composition of as-fabricated PAPTF can be modified significantly by applying different deposition conditions, such as concentration ratio of Ag(I) to Pd(II) ions in electrolytic solution and deposition time.
