Summary: The conversion from metal nanocluster catalysts to metal single-atom catalysts is an important step in the rational design of atomically dispersed metal catalysts. A continuous and convenient method was reported to transfer Pd nanoclusters into Pd single-atoms through ligand assisted annealing, reducing its activating temperature to 400 degrees C. The structural evolution of Pd species throughout the atomization process was comprehensively monitored using ex-situ microscopy and spectroscopy. Theoretical calculations revealed that the presence of remaining Cl ligands caused structural instability, leading to the low-temperature transformation.

Summary: Heterogeneous solid catalysts based on atomically dispersed Pd species are widely used in selective alkyne hydrogenation. However, lack of structural analysis tools and a unified synthetic system has hindered the understanding of their structure-activity relationship. In this study, we developed a convenient method to obtain Pd nanoclusters and Pd single atoms loaded on a nitrogen-doped carbon support and explored their structure-activity relationship in phenylacetylene hydrogenation. The results showed that Pd nanoclusters exhibited much higher mass activity compared to Pd single atoms, and steric hindrance played a crucial role in their catalytic performances.

Summary: As an external field, a magnetic field can influence the electrocatalytic activity of catalysts through various effects, such as electron spin polarization. In this study, we investigate the sensitive response behavior of Cu2O nanocubes to an in situ magnetic field. The results show that a strong magnetic field increases the transferred electron quantity and current density, while decreasing the onset potential. Additionally, the magnetic field alters the product selectivity, with an increase in the Faraday efficiency of C-1.
