“…In previous reports, only when the light irradiation intensity exceeds 14 suns did the CO production rate of photothermal RWGS surpass 100 mmol g −1 hour −1 . Therefore, the 1-sun–driven photothermal RWGS CO production rate (1065 mmol g −1 hour −1 ) over 2D Ni 1 Ag 0.02 O 1 is not only far superior to the reported advanced value under weak sunlight irradiation (1.01 mmol g −1 hour −1 under 1-sun irradiation) ( 43 ) but also higher than the best value of advanced catalysts under concentrated sunlight irradiation (978.4 mmol g −1 hour −1 under 28 suns irradiation) ( 19 ). Because the 2D Ni 1 Ag 0.02 O 1 can be scalable synthesized (fig.…”

The scalable artificial photosynthesis composed of photovoltaic electrolysis and photothermal catalysis is limited by inefficient photothermal CO 2 hydrogenation under weak sunlight irradiation. Herein, NiO nanosheets supported with Ag single atoms [two-dimensional (2D) Ni 1 Ag 0.02 O 1 ] are synthesized for photothermal CO 2 hydrogenation to achieve 1065 mmol g −1 hour −1 of CO production rate under 1-sun irradiation. This performance is attributed to the coupling effect of Ag-O-Ni sites to enhance the hydrogenation of CO 2 and weaken the CO adsorption, resulting in 1434 mmol g −1 hour −1 of CO yield at 300°C. Furthermore, we integrate the 2D Ni 1 Ag 0.02 O 1 -supported photothermal reverse water-gas shift reaction with commercial photovoltaic electrolytic water splitting to construct a 103-m 2 scale artificial photosynthesis system (CO 2 + H 2 O → CO + H 2 + O 2 ), which achieves more than 22 m 3 /day of green syngas with an adjustable H 2 /CO ratio (0.4-3) and a photochemical energy conversion efficiency of >17%. This research charts a promising course for designing practical, natural sunlight–driven artificial photosynthesis systems.

Catalytic conversion of carbon dioxide (CO 2 ) into useful chemical raw materials or fuels can help achieve the "dual carbon" goals of carbon peaking and carbon neutrality. As a sustainable green energy source, solar energy provides energy for human production and life. In recent years, the reported single-atom catalysts (SACs) have higher atom utilization and better catalytic efficiency than traditional heterogeneous catalysts. In the field of photocatalysis and photothermal synergistic catalysis of CO 2 conversion, single-atom catalysts can reduce the reaction temperature and pressure, improve the catalytic activity, and improve the selectivity of the reaction. In this mini-review, the basic mechanism and classification of CO 2 reduction are introduced, and then the roles and differences of single-atom catalysts in photocatalysis and photothermal catalysis are introduced. In addition, according to the reduction product types, the recent research progress of single-atom catalysts in photoconversion and photothermal CO 2 conversion was reviewed. Finally, the challenges of monoatomic photocatalytic and photothermal CO 2 reduction technologies have prospected. This mini-review hopes to provide an in-depth understanding of the roles of single atoms in photocatalysis and photothermal catalysis and to shed light on the actual production and application of renewable energy. High-performance single-atom catalysts are expected to achieve industrial applications of CO 2 conversion, which will contribute to the early realization of the two-carbon goal.

“…Apart from the above-mentioned applications, Xene-based SACs have also showed intriguing performance in other catalytic fields, such as NO 3 RR, [57,97,281] RWGS, [151] CO oxidation, [100,282] and hydrazine oxidation reaction, [51] because of their maximized atom utilization (≈100%), unique electronic structure and fascinating properties that differ from their NPs counterparts. Recently, 2D BP was employed as a giant P ligand to load high-density PdCu dual-atom to form a PdCuP 4 coordination structure, which achieved NO 3 − removal rate 96.3% of and N 2 selectivity of 95.2%.…”

“…Long-term measurement in Figure 20h showed negligible decay for the Se SA-NCM-1000-based OHzFC after continuous test for 6 h, demonstrating that the Se SA-NCM-1000-based OHzFC has robust structural stability for OHzFCs. Furthermore, in 2022, Li et al [151] rationally designed and successfully fabricated Bi SA-CeO 2 by a template method, which exhibited impressive activity and stability for RWGS under air corrosion at 400°C, demonstrating extraordinary oxidation resistance.…”

In recent years, the emergence of novel two‐dimensional monoelemental materials (Xenes), e.g., graphdiyne, borophene, phosphorene, antimonene, bismuthene, and stanene, has exhibited unprecedented potentials for their versatile applications as well as addressing new discoveries in fundamental science. Owing to their unique physicochemical, optical and electronic properties, emerging Xenes have been regarded as promising candidates in the community of single‐atom catalysts (SACs) as single‐atom active sites or support matrixes, for significant improvement in intrinsic activity and selectivity. In order to comprehensively understand the relationships between structure and property of Xene‐based SACs, this review represents a comprehensive summary from theoretical predictions to experimental investigations. Firstly, theoretical calculations regarding both the anchoring of Xene‐based single‐atom active sites on versatile support matrixes and doping/substituting heteroatoms at Xene‐based support matrixes are briefly summarized. Secondly, controlled synthesis and precise characterization are presented for Xene‐based SACs. Finally, current challenges and future opportunities for the development of Xene‐based SACs are highlighted.This article is protected by copyright. All rights reserved
