  • Abstract A Pd based electrocatalyst was synthesized on ZrO2 modified MWCNTs support for the application as anodic catalyst in direct formic acid fuel cells and electrocatalytic hydrodechlorination. X-ray diffraction (XRD) analysis, field emission scanning electron microscopy, and high resolution electron microscopy (HRTEM) were executed to analyze the structures and morphologies of the nanoparticles. The electrocatalytic performance can be measured by cyclic voltammetry (CV) and high performance liquid chromatography.
    From the high resolution images, the particle diameters are about 10 ~ 30 nm for Pd and AuPd catalysts. For polyol synthesized catalysts, polyol-Pd/MWCNTs have the highest current density, and polyol-Pd/ZrO2/MWCNTs have the lower open circuit potential. The photo synthesized 1A-AuPd/ZrO2/MWCNTs have excellent performance in HCOOH/H2SO4 and have the highest current density of 583.33mA/mg Pd at 0.297V.
    The best performance catalyst of 1A-AuPd/ZrO2/MWCNTs was selected to catalyze the hydrodechlorination reaction. The peak at 0.5 V is the reaction of formic acid oxidation. There shows a weak current during the reaction. From HPLC analysis, the 4-chlorophenol conversion can be evaluated as 30.32%.
