This invention belongs to the field of catalyst materials technology, specifically relating to a Pd-UiO-66 particle electrode, its preparation method, and its application. The Pd-UiO-66 particle electrode uses a zirconium-based metal-organic framework UiO66 as a support. Palladium nanoparticles are obtained by reducing palladium salts with sodium borohydride. The palladium nanoparticles are then reacted with the hydroxyl groups on the polyvinyl alcohol molecules. 2+ The coordination between the components and the steric hindrance effect of the long-chain molecules of polyvinyl alcohol regulate the dispersion of palladium nanoparticles, allowing palladium nanoparticles to be loaded onto UiO66 to obtain Pd-UiO-66. The Pd-UiO-66 particle cathode in this invention avoids the aggregation of palladium nanoparticles, greatly increasing the electrode area / solution volume ratio and helping to provide more active sites for dechlorination.
