TLDR
In this article, a comparison of single-atom catalysts with conventional heterogeneous catalysts in catalytic CO2 reduction is made and discussed, showing a broad prospect in the field of catalysis.Abstract:
Single‐atom catalysts (SACs) have attracted extensive attention since their emergence. During the single‐atomic catalytic process, the “active center” exists in the form of atomical monodispersion, with nearly 100 % utilization of metal atoms. Uniform and atomically dispersed catalytic centers give SACs pronounced reaction activity and chemical selectivity. Here, we review the development processes, synthetic strategies, characterization methods, and applications of SACs in CO2 reductive upgrading. Also, a comparison of SACs with conventional heterogeneous catalysts in catalytic CO2 reduction is made and discussed. SACs have built a bridge between homogeneous and heterogeneous catalysis and have the advantages of both, showing a broad prospect in the field of catalysis.read more

TL;DR: Density functional theory calculations show that the high catalytic activity correlates with the partially vacant 5d orbitals of the positively charged, high-valent Pt atoms, which help to reduce both the CO adsorption energy and the activation barriers for CO oxidation.
