“…This can be a common issue in studies aimed at examining solely the properties of SA in catalysts actually presenting a distribution of structures. A similar synergy was reported for other reducing agents such as NaBH 4 for 4‐nitrophenol reduction on Pd SA+NP /C catalysts, [60] or hydrazine on Mo SA MoO 2‐NP /N−C catalysts for transfer hydrogenation [61] . Interestingly, when using hydrazine as reducing agent on Fe SA ‐Fe 2 O 3‐NP /N−C catalysts for selective reduction of nitro compounds, an opposite situation was observed.…”

In that case, it is the Fe SA that generate hydrogen by hydrazine decomposition and the nitrobenzene reduction to aniline is performed on Fe 2 O 3-NP surface.…”

Catalytic active sites consisting in isolated metal single atoms can be found in enzymatic, homogenous and heterogeneous catalysts. In heterogeneous catalysis, single‐atom catalysts (SACs) may offer high reactivity and selectivity towards some reactions provided their local coordination environment and electronic properties are correctly tuned. These sites generally possess specific properties compared to metal nanoparticles or clusters. Because of the difficulty, inherent in supported catalysis, of preparing catalysts having a high homogeneity of active sites, these two species have had to coexist in many supported catalysts. If the current trend is often limited to comparing the reactivity of these two types of species, we will see in this mini‐review that for few years, work has highlighted a possible synergy between these species to improve catalytic performance. The different types of synergies are discussed, as well as challenges and opportunities for such catalysts in thermal‐, electro‐ and photo‐catalysis.

“…In recent years, single-atom catalysts (SACs) have attracted much attention in many catalysis areas for their maximum atom utilization efficiency, uniform active sites, and excellent catalytic activity. [16][17][18] The electronic and coordination synergy between the metal single atoms (SAs) and the support in SACs can substantially enhance the catalytic performance. [19] Tang et al [20] synthesized single atom Pt-loaded MgO nanosheets for toluene oxidation, and found that as more oxygen vacancies are created by the doping of Pt, molecular oxygen is activated and more reactive oxygen species are produced.…”

This study adopts a facile and effective in situ encapsulation-oxidation strategy for constructing a coupling catalyst composed of atomically dispersed Pt-doped Co 3 O 4 spinel nanoparticles (NPs) embedded in polyhedron frames (PFs) for robust propane total oxidation. Benefiting from the abundant oxygen vacancies and more highly valent active Co 3+ species caused by the doping of Pt atoms as well as the confinement effect, the optimized 0.2Pt-Co 3 O 4 NPs/PFs catalyst exhibits excellent propane catalytic activity with low T 90 (184 °C), superior apparent reaction rate (21.62×10 8 (mol g cat −1 s −1 )), low apparent activation energy (E a = 17.89 kJ mol −1 ), high turnover frequency ( 811×10 7 (mol g cat −1 s −1 )) as well as good stability. In situ diffuse reflectance infrared Fourier transform spectroscopy and density functional theory calculations indicate that the doping of Pt atoms enhances the oxygen activation ability, and decreases the energy barrier required for C-H bond breaking, thus improving the deep oxidation process of the intermediate species. This study opens up new ideas for constructing coupling catalysts from atomic scale with low cost to enhance the activation of oxygen molecules and the deep oxidation of linear short chain alkanes at low temperature.
