The synthesis of single-atom catalysts for heterogeneous catalysis

Abstract

Heterogeneous catalysis is an important class of reactions in the industrial production, especially in green chemicals synthesis, environmental, and organic catalysis. Single-atom catalysts (SACs) have emerged as promising candidates for...

Practical applications of total internal reflection fluorescence microscopy for nanocatalysis

“…As for application to the nanocatalysis field, multi-layered interfaces are sometimes involved. [41][42][43] For example, if medium 1 is indium tin oxide (ITO) with a nanometer-thick middle layer, TIR will occur regardless of the refractive index of the middle layer.…”

Single‐Atom Catalysis in Organic Synthesis

“…[6] Support engineering is thus crucial for synthesiz-ing stable SACs. [7] Common supports often include soft materials with high surface area and active anchoring groups, such as carbon nitrides, covalent and metal organic frameworks, and graphene layers. [8] Besides, by controlling the support structure, it becomes possible to regulate the surface free energy of the isolated atoms against aggregation and clustering.…”

Isolated iron single-atom sites for oxygen reduction derived from a porphyrin-based carbon sphere by a polymerization–coordination–pyrolysis strategy

“…Metal isolated single-atom site (ISAS) catalysts, 1,2 as a new frontier in catalysis, have aroused intensive interest. [3][4][5][6][7][8][9][10] During catalysis, only the metal atoms on the surface of metal nanomaterials can participate in catalysis. As the sizes of metal nano-materials gradually decrease from nano-particles to nanoclusters, the proportion of supercial metal atoms increases, with the atom utilization efficiency during catalysis gradually increasing.…”
