Summary: Scanning tunneling microscopy was used to compare the evolution of Pd islands on Ag(111) and Au(111) surfaces. Different behaviors were observed, with large Pd islands and vacancy pits forming on Ag(111), while smaller Pd islands and no vacancy pits were observed on Au(111). The annealing process resulted in Pd diffusion into the subsurface for both surfaces, but the behavior on Au(111) was significantly different due to the herringbone reconstruction providing higher binding energy sites.

Summary: This study investigates the two-step electrosynthesis of metal nanoparticle nanocomposites with iron oxide-hydroxide FeO-xFe(OH)(2). The first step involves the synthesis of amorphous FeO-xFe(OH)(2) using a soluble Fe-anode and atmospheric oxygen in an undivided cell. The second step is mediated electrosynthesis of metal nanoparticles in the resulting FeO-xFe(OH)(2) solution, with the nature of the mediator determining the efficiency. The formed M/FeO-xFe(OH)(2) nanocomposites exhibit different characteristics depending on the metal and presence of cetyltrimethylammonium chloride (CTAC). The Pd@CTAC/FeO-xFe(OH)(2) nanocomposite shows high catalytic activity in the reduction reaction of p-nitrophenol by sodium borohydride, which can be enhanced by increasing the concentration of CTAC.

Summary: In this study, a series of Mn-doped La2CuO4 perovskite catalysts with adjustable electronic structure were prepared to explore the effects of catalyst intrinsic electronic structure evolution on molecular oxygen activation. The results showed that LaMn0.5Cu0.5O3 catalyst exhibited the best propylene oxide selectivity at 150 degrees C. Characterization and DFT calculations revealed that the excellent catalytic performance of LaMn0.5Cu0.5O3 could be attributed to the change of molecular oxygen activation sites from oxygen vacancy active sites on La2CuO4 to Cu active sites on LaMn0.5Cu0.5O3, and the synergistic interaction between manganese and copper that affected the electron density on Cu sites and modulated the activated states of surface adsorbed oxygen species. Crystal band theory was also employed to associate the oxygen vacancy density with the Cu valence state.

Summary: Metal-organic frameworks (MOFs) have been studied for their thermal decomposition behaviors, particularly in the presence of Pt nanoparticles. The addition of Pt was found to promote the decomposition of Cu-BTC, Co-BTC, and Zn-BTC in air atmosphere, while having a different effect on Ce-BTC. In-situ DRIFTS showed that the introduction of Pt changed the thermal decomposition modes of MOFs. Furthermore, it was observed that Cu-BTC, Co-BTC, and Zn-BTC exhibited improved thermostability in hydrogen atmosphere due to the hydrogenation of the carboxylate on the organic linkers.

Summary: The ligand protected AgCuCl nanocluster was synthesized and loaded onto BaCO3 to prepare a small size bimetal catalyst. Under N-2 atmosphere, a PO selectivity of 85.29% at 275 degrees C was achieved. The low-valence Cu+ species in the catalyst facilitated the formation of electrophilic oxygen species, resulting in the production of PO instead of byproducts. This study demonstrates the use of supported bimetal catalysts in propylene epoxidation and provides guidance for selecting supports for efficient catalysts.
