Article Abstract

Single-atom catalysis has become a new branch in heterogeneous catalysis. Although the naturally produced SiO -based materials are abundant and stable, fabrication of single-atom catalysts on such supports with high loading remains as a formidable challenge due to the lack of bonding sites to anchor the isolated metal species. Herein, modifying the diatomite, a kind of pure SiO mineral, with CeO nanoparticles is demonstrated to increase the defect sites on the support. The enhanced metal-support interaction maintains the atomic dispersion of Pt species with above 1 wt.% loading, exhibiting good performance in the selective hydrogenation of phenylacetylene to styrene.

Transition metal single-atom catalysts (TM-SACs) have emerged as promising electrocatalysts for the two-electron oxygen reduction reaction (2eORR) due to their exceptional atomic utilization efficiency and tunable electronic structures. Nevertheless, the practical application of TM-SACs is constrained by their relatively low metal loading, which adversely affects their catalytic performance. Herein, we developed a universal defect-mediated strategy to fabricate TM-SACs with high metal loading.

The practical application of neutral Zn-air batteries (ZABs) is severely hindered by sluggish kinetics of oxygen reduction/evolution reaction (ORR/OER) and dendrite growth on the Zn anode. A precisely controlled preparation of Fe single atoms (FSAs) is achieved on a Fe-substituted HPWO∙nHO (abbr. {FePWO}) dotted Co/N doped carbon (Co-N-C), which ensures a well-dispersed, stable, and high loading (3.

Heterogeneous single-atom catalysts (SACs) have emerged as a new frontier in the field of energy-related catalysis owing to the maximum atomic utilization efficiency, unique electronic and geometric properties compared with traditional nano-catalysts. Nevertheless, it is still a great challenge to fabricate high-loading SACs, since these isolated metal sites with high surface free energy are apt to assemble into clusters or particles with a high metal content. This review summarizes recent advancements for high-loading SACs, and mainly focuses on the synthetic strategies, unique interatomic interactions, together with their applications in different chemical reactions, including photocatalysis, electrocatalysis, and thermocatalysis.

The high-temperature limitations of single-atom catalysts (SACs) synthesis, primarily thermal aggregation and low metal loadings, are overcome by a novel room-temperature metal-exchange strategy. We leverage the weak Zn─N coordination in high-loading Zn SACs (12.10 wt%, synthesized via controlled ZIF-8 pyrolysis) as a platform for the facile exchange with a broad range of metals (Mn, Fe, Co, Ni, Cu, Ru, Pt, up to 12.
