Sub-nanometric materials: Electron transfer, delocalization, and beyond

Polyoxometalate-based nanostructures for electrocatalytic and photocatalytic CO 2 reduction

“…(ii) Note that cluster-based orderly assembly structure may exist large-scale electron delocalization 117 . The delocalized electrons could trigger exceptional electronic properties in catalysis applications due to important alterations in both the orbital of cluster unit and the total electronic distribution of assembly structure.…”

Recent progress of sub-1 nm nanomaterials: synthesis, polymer-analogue properties and applications in redox catalysis

“…SNMs can interact with the external field efficiently, which endows SNMs with outstanding catalytic and optical properties. SNMs have shown great potential for optics, 9 catalysis, 8 energy conversion 10 and mechanical applications. 11 Typically, SNMs can be classified into zero-dimensional (0D), one-dimensional (1D), and two-dimensional (2D) materials.…”

“…Electrons can be shared among the nearby building blocks of SNMs, resulting in large-area electron delocalization. 8 As a result, the electron structure can be finely tuned to achieve high catalytic activity. Furthermore, most atoms in SNMs are exposed on the surface.…”

Fabricating sub-nanometer materials through cluster assembly

“…[18][19][20][21][22] In addition, interactions between cluster building blocks can significantly affect their electronic structures and properties, leading to the enhanced properties of cluster-based assemblies compared to individual building blocks. [23][24][25] Polyoxometalate (POM) and noble metal clusters are subnanometer metal oxide and metal nanoparticles, respectively, with atomic precision structures and geometries. 26,27 As the most representative cluster species, the synthesis and assembly of POM and noble metal clusters have been comprehensively studied in the past few decades.…”
