N2 - In this study, a Nickel foam electrode modified with MnO2 and Pd (i.e., a foam Ni/MnO2/Pd electrode) was fabricated in two electrodeposition steps. First, MnO2 was deposited on a three-dimensional cross-linked Ni foam electrode with high porosity and surface area through cyclic voltammetry. Then, the constant current method was used to deposit Pd electrically on the Ni foam electrode. The foam Ni/MnO2/Pd cathode exhibited a phenol degradation rate of 91.6% at a current density of 2 mA/cm2 for 2 h. This phenol degradation rate was higher than those of foam Ni/MnO2 and foam Ni/Pd. Furthermore, the Pd on the foam Ni/MnO2/Pd cathode was immobilized by depositing another thin layer of MnO2 to form foam Ni/MnO2/Pd/MnO2, which reduced Pd loss in the cleaning process and improved reusability without decreasing the phenol degradation efficiency.
