Abstract—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 electro-
catalytic 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. Mor-
phology 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.
