“…Lin and co‐workers prepared a class of template‐free mesoporous carbon nanorods possessing isolated Ni‐N x sites and Ni nanoparticles, by pyrolyzing the rectangular nickel dimethyglyoximate (Ni(dmgH) 2 ) nanorods. [ 86 ] Some large Ni particles could be removed by strong acid etching, and a composite‐type material with the presence of both single‐atom Ni and smaller Ni nanoparticles was obtained. Such a simple synthesis process for achieving dual active species could roughly tune the ratio of single‐atom sites to nanoparticles by controlling the leaching time.…”

Single‐atom catalysts, featuring some of the most unique activities, selectivity, and high metal utilization, have been extensively studied over the past decade. Given their high activity, selectivity, especially towards small molecules or key intermediate conversions, they can be synergized together with other active species (typically other single atoms, atomic clusters, or nanoparticles) in either tandem or parallel or both, leading to much better performance in complex catalytic processes. Although there have been reports on effectively combining the multiple components into one single catalytic entity, the combination and synergy between single atoms and other active species have not been reviewed and examined in a systematic manner. Herein, in this overview, the key synergistic interactions, binary complementary effects, and the bifunctional functions of single atoms with other active species are defined and discussed in detail. The integration functions of their marriages are investigated with particular emphasis on the homogeneous and heterogeneous combinations, spatial distribution, synthetic strategies, and the thus‐derived outstanding catalytic performance, together with new light shined on the catalytic mechanisms by zooming in several case studies. The dynamic nature of each of the active species and in particular their interactions in such new catalytic entities in the heterogeneous electrocatalytic processes are visited, on the basis of the in situ/operando evidence. Last, we feature the current challenges and future perspectives of these integrated catalytic entities that can offer guidance for advanced catalyst design by the rational combination and synergy of binary or multiple active species.

“…Nevertheless, there comes another idea that M‐N‐C containing both the single metal atoms and nanoparticles can be directly applied for syngas synthesis via CO 2 RR in an aqueous solution. [ 114 , 115 ] Compared with CO 2 electroreduction, CO 2 and water coelectroreduction into syngas is more practical as syngas has been extensively used for industrial production of various hydrocarbons. A series of mesoporous N‐doped carbon nanorods containing both single Ni atoms and Ni NPs were synthesized and used for controlled syngas production from CO 2 and water.…”

“…A series of mesoporous N‐doped carbon nanorods containing both single Ni atoms and Ni NPs were synthesized and used for controlled syngas production from CO 2 and water. [ 114 ] The syngas with different ratios of CO to H 2 could be varied from 1:9 to 19:1 by changing the ratio of single Ni atoms to Ni NPs from 1:4.9 to 1:0 via adjusting the acid leaching time (Figure 15b ).…”

Electrochemical Reduction of CO₂ to CO over Transition Metal/N‐Doped Carbon Catalysts: The Active Sites and Reaction Mechanism

Electrochemical CO2 reduction to value‐added chemicals/fuels provides a promising way to mitigate CO2 emission and alleviate energy shortage. CO2‐to‐CO conversion involves only two‐electron/proton transfer and thus is kinetically fast. Among the various developed CO2‐to‐CO reduction electrocatalysts, transition metal/N‐doped carbon (M‐N‐C) catalysts are attractive due to their low cost and high activity. In this work, recent progress on the development of M‐N‐C catalysts for electrochemical CO2‐to‐CO conversion is reviewed in detail. The regulation of the active sites in M‐N‐C catalysts and their related adjustable electrocatalytic CO2 reduction performance is discussed. A visual performance comparison of M‐N‐C catalysts for CO2 reduction reaction (CO2RR) reported over the recent years is given, which suggests that Ni and Fe‐N‐C catalysts are the most promising candidates for large‐scale reduction of CO2 to produce CO. Finally, outlooks and challenges are proposed for future research of CO2‐to‐CO conversion.

“…4 The electroreduction of CO 2 into syngas has been studied widely, but this requires an additional bias to drive the reduction. 4,5 Alternatively, photocatalytic CO 2 reduction using sunlight and semiconductors as catalysts has been studied for the direct conversion of CO 2 into value-added products. 6 Most photocatalysts so far are either inorganic materials or molecular metal-organic compounds.…”
