Single-atom catalyst, which makes exceptionally efficient use of expensive noble metals and can bring out unique properties, is a new frontier in heterogeneous catalysis, a commonly used catalytic reaction in industry. However, applications of single-atom catalysts are usually compromised by limited cat...
Despite intense research, the relation of structure-activity for single-atom catalysts (SACs) still bedazzles researchers, since diversified configurations of active sites would bring about difficulty in structural identification and theoretical simulations. Here, recent results on the applications of SACs ...

Single-atom catalysis, the catalysis by single-atom catalysts(SACs), has attracted considerable attention in recent years as a new frontier in the heterogeneous catalysis field. SACs have the advantages of both homogeneous catalysts(isol... F Chen,X Jiang,L Zhang,... - 《Chinese Journal of Ca...
The characterizations of the reused catalysts show that the Ni-N-C-600 structure remains intact; single atoms of Ni are still highly dispersed and no aggregation is observed (Fig. 1.7B). The unchanged X-ray photoelectron spectroscopy (XPS), EXAFS, and XANES profiles of the Ni-N-C-600 ...
Single-atom catalysts with uniform ACSs are favorable for studying the nature of ACSs12,13,14. Wark et al.13reported that a single-atom V1/ZSM-5 catalyst had significant SCR activity, implying the mononuclear active sites, but its activity is much lower than that over V2O5/TiO2with abundant...
Reducing the size of metal nanoparticles down to the single-atom level has been actively pursued to maximize the use of precious metals. Recently, single-atom catalysts, in which all the metal atoms are isolated on a support with 100% dispersion, have received much attention. However, the lack...
