Continuous Flow Liquid-Phase Semihydrogenation of Phenylacetylene over Pd Nanoparticles Supported on UiO-66(Hf) Metal-Organic Framework

Akkenapally Swamy et al.

Summary: Catalysis under continuous flow operation is more relevant in industry, especially for semi hydrogenation reactions. However, catalysis with metal-organic frameworks (MOFs) is mostly restricted to batch reactions. In this study, Pd nanoparticles (NPs) were anchored on UiO-66(Hf) MOF to create an effective catalyst for semi hydrogenation of phenylacetylene into styrene. The Pd/UiO-66(Hf) catalyst showed excellent catalytic performance, with high phenylacetylene conversion (99.0%) and styrene selectivity (90.0%), and demonstrated lower deactivation rate compared to other reported materials. The strong metal-support interaction between the MOF and Pd nanoparticles contributed to the higher stability of Pd/UiO-66(Hf) catalyst.

Pyridinic Nitrogen Sites Dominated Coordinative Engineering of Subnanometric Pd Clusters for Efficient Alkynes' Semihydrogenation

Rui Zhang et al.

Summary: Supported metal catalysts, especially nitrogen-doped carbon support materials, have been extensively studied for optimizing the selective semihydrogenation of alkynes. It remains a challenge to identify the dominant nitrogen configuration that affects the catalytic behavior. In this study, uniform mesoporous N-doped carbon spheres were used as supports to immobilize subnanometric Pd clusters, revealing that pyridinic nitrogen configuration plays a crucial role in enhancing catalytic activity and selectivity. The presence of abundant coordination sites and the electron effect between pyridinic nitrogen sites and Pd clusters contribute to the improved catalytic performance.

The promotion effect of π-π interactions in Pd NPs catalysed selective hydrogenation

Miao Guo et al.

Summary: The utilization of weak interactions to improve the catalytic performance is crucial but challenging. This study demonstrates that by using imine-linked covalent organic frameworks, the weak interactions near Pd nanoparticles can be finely tuned. The pi-pi interaction between the organic frameworks and the substrate significantly reduces the activation barrier, thus enhancing the catalytic activity.
