“…The X-ray absorption near-edge spectroscopy (XANES) spectra (Figure c) exhibited that the Pd K-edge absorption of Pd 1 /FeO x -10 was similar to that of PdO, implying that the Pd valence was around +2 . With the help of XPS analysis (Figure d) of the Pd (3d 5/2 ) region of Pd 1 /FeO x -10, it was revealed that the valence of Pd was +2 (with a binding energy of 337.2 eV), , in line with the XANES results. In addition, the Pd content of Pd 1 /FeO x -10 was measured by ICP-OES to be 0.24 wt %.…”

Palladium single-atom catalysts (SACs) have caught great attention owing to their maximal atom utilization and outstanding activity for the Suzuki–Miyaura cross-coupling reaction. However, a facile manufacturing method for kilogram-scale synthesis of noble metal SACs with high productivity is still in demand. This study reports on the synthesis of SACs by direct ball milling of commercial metal oxides and nitrate precursors with a productivity of ∼100%. The as-prepared Pd1/FeO x SACs show high catalytic performance (the TOFs are 7844 h–1), high stability, and general applicability for the Suzuki–Miyaura cross-coupling reaction under mild conditions. More encouragingly, kilogram-scale Pd1/FeO x SACs can be synthesized in one batch by this approach, endowing great potential for industrial applications. Furthermore, the preparation of Pt, Ru, and Rh SACs is also successfully carried out via the ball milling method, demonstrating favorable applicability. Our findings illustrate exciting chances presented by the highly efficient synthesis of SACs for the formation of C–C bonds.

Selective hydrogenation has a long history of being an important reaction process for the preparation of high-value chemicals. The geometric and electronic structures of the catalysts largely determine their basic catalytic performance, including activity, selectivity, and stability. However, the complexity of the components and structures of the catalytic active sites poses a significant challenge to the characterization and the sequential performance attribution. On the basis of summarizing the geometric and electronic structure research in this field, this Review will pay special attention to the adsorption and activation modes of reactants, reaction kinetics, identification and classification of structural sensitivity, methods for geometric and electronic regulation, and distinctive concepts for catalyst design, to enlighten the further development of high-efficiency hydrogenation catalysts.
