报告题目：Super valence bond theory
We proposed a new concept for bonding between superatoms—super valence bond (SVB), of which superatoms can share both valence pairs and nuclei for shell closure thus forming delocalized super bonding.] Using Li clusters as a test case, we theoretically find that metal clusters can mimic the behavior of simple molecules in electronic shells. It is found that Li14, Li10, and Li8 clusters are analogues of F2, N2, and CH4 molecules, respectively, in molecular orbital (MO) diagrams and bonding patterns. This new concept shows new insights in understanding the stability of clusters and designing the cluster-assembling materials.
题目：The design and synthesis of metal–organic framework (MOF)-based metal nanomaterials, and their applications in industrial catalysis
Abstract: Our group focus on the design and synthesis of metal–organic framework (MOF)-based metal nanomaterials, and their applications in industrial catalysis. Aiming at the bottleneck problems of common industrial hydrogenation and oxidation catalysts, including easy agglomeration and poor activity of metal active centers, harsh reaction conditions and poor selectivity, we proposed new concepts of synergistic nanopore confinement and pore surface stabilization effect, synergistic pore decoration and diffusion enhancement effect, and controlled deligandation to improve the efficiency of MOF-based metal catalysts, leading to the construction of MOF-based metal catalysts with high stability, high activity and high selectivity to further promote the industrial applications of MOF-based metal catalytic materials.
