“…It was observed that the relatively weak peak at 690 and 730 cm −1 emerged after AgCuCl was loaded onto the BaCO 3 , which was probably caused by the substitution of benzene rings of ligands in the AgCuCl. 32,43 Surprisingly, when AgCuCl/BaCO 3 was heated in a N 2 atmosphere, the intensity of these two peaks decreased, indicating that the ligands were removed during the preparation process of AgCuCl/BaCO 3 -N 2 .…”

Direct epoxidation of propylene (DEP) into propylene oxide using molecular oxygen is a promising approach due to high atom utilization and environmental sustainability. However, the absence of highly selective catalysts has been a challenge in this field. Herein, the ligand protected AgCuCl nanocluster was synthesized via a one-pot method and loaded onto BaCO 3 to prepare a small size bimetal catalyst (AgCuCl/BaCO 3 -N 2 ) via calcination under N 2 atmosphere. A PO selectivity of 85.29% at a relatively mild temperature of 275 °C can be obtained. Characterizations revealed that AgCuCl/BaCO 3 -N 2 with low-valence Cu + species facilitated the formation of electrophilic oxygen species that preferentially attacked the C�C bond of propylene, resulting in the production of PO instead of attacking the C−H bond for the formation of byproduct. This study provides a clear example of using supported bimetal catalysts to achieve propylene epoxidation and offers guidance for selecting supports for supported nanoclusters as an efficient catalyst.

“…Fine-tuning of the charge transport in metal-molecule-metal junctions is an eternal theme of molecular electronics. [1][2][3][4][5][6][7][8][9][10][11][12] Tremendous approaches have been developed to realize this goal, such as in situ chemical reactions, light-induced transformation, quantum interference effects and so on. The quantum interference (QI) effects featured by constructive quantum interference (CQI) and destructive quantum interference (DQI) have promising potential for rational design of advanced functional devices such as transistors, molecular switches and thermoelectric devices.…”
The charge transport of cobalt-bridged organometallic molecular wires is investigated, and the experimental results show that the cobalt-bridge contributes a negative effect on the conductance and tunes the QI effects of the wires.
“…Charge transport in the single molecule-junction is at the heart of molecular electronics. [1][2][3][4][5][6][7][8][9][10][11] The molecule/electrode interface has severe impact on the charge transport and functioning of the single-molecule junction. The common strategies to tune the molecule/electrode interface are to change the electrodes or the anchoring group of molecules.…”
Here, we report the molecule - electrode interface of single-molecule junction can be regulated by side chain. Based on this regulation, a single-molecule junction probe, PyCHO, is developed, which can...
