Recently, under the guidance of Zheng Yanzhen, a professor at the Frontier Institute of Xi'an Jiaotong University, postdoctoral Chen Weipeng successfully prepared a case of high-nucleus transition-rare earth mixed metal nanoclusters under solvothermal conditions using the "mixed ligand" strategy. The cluster molecule is in the form of a six-pointed star, which is the second largest 3d-4f mixed metal cluster reported so far. While having good solution stability, the cluster contains a large amount of rare-earth gadolinium element, which has good performance in low-temperature magnetic refrigeration Application potential.
The research results were published in the "Journal of the American Chemical Society" in the form of a cover article.
High-nuclear transition-rare-earth mixed metal clusters, with their complex molecular structure, uniform size, and unique properties, have become a system eagerly constructed by cluster chemistry researchers. Among them, the ring-shaped structure has attracted much attention due to its special chemical and physical properties, but the 3d-4f mixed metal with a core-shaped structure exceeding 100 and having a ring-shaped structure has not been reported.
This study also used periodic density functional theory and cyclic voltammetry to explain the catalytic mechanism. According to reports, this work not only provides a new idea for the design and synthesis of 3d-4f mixed metal clusters, but also provides a reference and theoretical basis for the exploration of the solution stability, catalytic performance and functional expansion of rare earth-based nanoclusters.
