Insight into the Effects of Pd Single-atom Particles in the Activation of the Carbon-Chloride Bond

Abstract Palladium (Pd) shows high activity in a variety of catalysis reactions that refer to the activation carbon-halogenation bond, and single-atom Pd catalysts have received significant attention as new technology. Nevertheless, there is huge knowledge gap regarding which sites could form highly reactive centers. It unclear whether are active this process or not. In study, we synthesized Pd/TiO2 nanosheets with loadings 1%, 5%, 10% designed single atom nanoparticles on similar substrates. A scanning transmission electron microscope was used characterize catalysts. As catalyst, featuring NPs showed activating carbon-halogen bond carbon-chloride whereas atoms very low pros. Accordingly, our results demonstrate bonds cannot be catalyzed by emphasize significance ensemble effect determining sites.
