Understanding Single-Atom Catalysis in View of Theory

JACS Au, Journal Year: 2021, Volume and Issue: 1(12), P. 2130 - 2145

Published: Nov. 22, 2021

In the past decade, isolated single atoms have been successfully dispersed on various substrates, with their potential applications being intensively investigated in different reactions. While essential target of research single-atom catalysis is precise synthesis stable catalysts (SACs) clear configurations and impressive catalytic performance, theoretical investigations also played important roles identifying active sites, revealing mechanisms, establishing structure–activity relationships. Nevertheless, special attention should still be paid works to particularity SACs. this Perspective, we will summarize progress made understanding rich phenomena catalysis. We focus determination local structures SACs via comparison between experiments simulations, discovery distinctive mechanisms induced by multiadsorption, synergetic effects, dynamic evolutions, name a few, proposal criteria for theoretically designing SACs, extension original concepts hope that Perspective inspire more in-depth thinking future studies

Nano-Micro Letters, Journal Year: 2022, Volume and Issue: 15(1)

Published: Dec. 1, 2022

The sustainable production of green hydrogen via water electrolysis necessitates cost-effective electrocatalysts. By following the circular economy principle, utilization waste-derived catalysts significantly promotes development energy. Currently, diverse have exhibited excellent catalytic performance toward evolution reaction (HER), oxygen (OER), and overall (OWE). Herein, we systematically examine recent achievements in electrocatalysts for electrolysis. general principles design efficient are discussed, followed by illustration current strategies transforming wastes into Then, applications (i.e., carbon-based catalysts, transitional metal-based heterostructure catalysts) HER, OER, OWE reviewed successively. An emphasis is put on correlating catalysts' structure-performance relationship. Also, challenges research directions this booming field finally highlighted. This review would provide useful insights design, synthesis, electrocatalysts, thus accelerate economy-driven energy scheme.

Synergy of dual-atom catalysts deviated from the scaling relationship for oxygen evolution reaction

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: July 24, 2023

Dual-atom catalysts, particularly those with heteronuclear active sites, have the potential to outperform well-established single-atom catalysts for oxygen evolution reaction, but underlying mechanistic understanding is still lacking. Herein, a large-scale density functional theory employed explore feasibility of *O-*O coupling mechanism, which can circumvent scaling relationship improving catalytic performance N-doped graphene supported Fe-, Co-, Ni-, and Cu-containing dual-atom namely, M'M@NC. Based on constructed activity maps, rationally designed descriptor be obtained predict homonuclear catalysts. Seven four possess high activities that minimum theoretical overpotential. The chemical structural origin in favor mechanism thus leading enhanced reaction been revealed. This work not only provides additional insights into fundamental mechanisms, also offers guideline accelerated discovery efficient

Surface Engineered Single‐atom Systems for Energy Conversion

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(16)

Published: Jan. 10, 2024

Abstract Single‐atom catalysts (SACs) are demonstrated to show exceptional reactivity and selectivity in catalytic reactions by effectively utilizing metal species, making them a favorable choice among the different active materials for energy conversion. However, SACs still early stages of conversion, problems like agglomeration low conversion efficiency hampering their practical applications. Substantial research focus on support modifications, which vital SAC stability due intimate relationship between atoms support. In this review, category supports variety surface engineering strategies employed SA systems summarized, including site (heteroatom doping, vacancy introducing, groups grafting, coordination tunning) structure (size/morphology control, cocatalyst deposition, facet engineering, crystallinity control). Also, merits single‐atom systematically introduced. Highlights comprehensive summary discussions utilization surface‐engineered diversified applications photocatalysis, electrocatalysis, thermocatalysis, devices. At end potential obstacles using field discussed. This review aims guide rational design manipulation target‐specific capitalizing characteristic benefits engineering.
