“…However, activation of the C–H on the terminal −CH 2 OH of glycerol has a higher energy barrier in its selective oxidation to glyceric acid. Luo et al fabricated a (Pt 1 –Pt n )/CeO 2 catalyst by an impregnation method, which showed significantly higher activity than those of the respective Pt 1 /CeO 2 and Pt/CeO 2 NCs in glycerol oxidation, offering a 183.7 h –1 TOF value . The synergism between Pt SAs and Pt clusters efficiently promoted the reaction, where Pt clusters adsorbed the primary C–O/CO bonds and the adjacent Pt SAs activated the C–H bonds, thus reducing the activation barrier of glycerol oxidation.…”

Among all renewable energy sources (e.g., solar energy, wind, and biomass), biomass is the only organic carbon resource which has great potential to partly replace nonrenewable fossil resources to produce high value-added chemicals and biofuels. Singleatom catalysts (SACs) have shown compelling prospects and arguably become one of the most active research fields in biomass chemical catalysis due to their fascinating strengths in maximum atomic utilization, highly efficient catalytic reactivity, high selectivity, and good stability. Numerous achievements about the SACs have recently been amassed, including advanced synthesis methods, characterization techniques, and theoretical calculation, allowing us to forecast their working mechanisms and the catalytic roles of metals and coordination sites in the catalytic process. Based on the relevant literatures on SACs over the past few years, this review summarizes the preparation methods of SACs and their catalysis applications for biomass conversions with a special focus on the structure−activity relationship and catalytic reaction mechanism as well as prospects for the future developments of SACs. This review provides fundamental information for the development of the SACs in biomass valorization, clearly stimulating the development in this emerging research field.

“…Finally, synergy in tandem requiring high proximity between SAs and NPs was also observed for glycerol selective hydrogenation to glyceric acid on Pt SA + NP /CeO 2 [93] and Pt SA + NP / CuÀ CuZrO x [16c] catalysts. In that case, some steps of the mechanism were proposed.…”

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.
