Supramolecular nanocapsules as two-fold stabilizers of outer-cavity sub-nanometric Ru NPs and inner-cavity ultra-small Ru clusters

Abstract

The synthesis of metallic nanoparticles (MNP) with high surface area and controlled shape is of paramount importance to increase their catalytic performance. The detailed growing process of NP is mostly...

Revealing Catalyst Self-Adjustment in C–S Cross-Coupling through Multiscale Liquid-Phase Electron Microscopy

“…It is worth noting that at the current research level in the field of nanochemistry and catalysis, transition-metal-based particles are considered not as separate species with their independent functionality but as an integral part of the complex multiscale chemical space created in reaction media. Discussing achievements in NP property modulation by different components of a chemical ensemble, decoration of NPs with organic ligand shell by Chaudret − and Han, − confinement of NPs in covalent organic and metal–organic frameworks by Jiang, − NP chemistry inside carbon nanoarchitectures by Khlobystov, − incorporation of NPs in complex ionic liquid (IL) environments, − and electron microscopy detection of NPs generated in situ in ILs , by Dupont, as well as application of NP-support and NPs–NPs cooperativity in the light energy delivery by Zhao − and Xu − and their colleagues can be mentioned as representative examples. The rational design of chemical transformations in such complex reaction environments is unthinkable without a clear understanding of the nature of the key phenomena occurring not only at the nanoscale but also at higher levels of matter organization.…”

Horizontal expansion of biicosahedral M13-based nanoclusters: resolving decades-long questions

“…[1][2][3][4][5][6][7][8] Besides, due to their programmably structure-dependent performances, metal nanoclusters or cluster-based hybrids have been customized for widespread applications such as catalysis, chemical sensors, drug delivery, biological imaging, and so on. [9][10][11][12][13][14][15][16][17][18] Typically, the structure of nanoclusters is composed of an internal metallic kernel and a peripheral ligand shell. [19][20][21][22][23][24][25][26][27][28][29][30] The structural determination of the metallic kernels of clusters at the atomic level has considerably inspired nanoscientists on a long-lasting question in nanoscience: what are the evolution modes from small-sized metallic complexes to nanoclusters or from nanoclusters to large-sized nanoparticles?…”
