“…However, as shown in Figure 8, RRDE experiments show that in 0.1 M HClO4, these catalysts are indeed highly selective to H2O2 production. 69,78,83 This discrepancy could suggest that additional kinetic barriers exist in acid electrolyte, that serve to preserve the O-…”

H2O2 is a valuable, environmentally friendly oxidizing agent, with a wide range of uses, from the provision of clean water to the synthesis of valuable chemicals. The on-site electrolytic production of H2O2 would bring the chemical to applications beyond its present reach. The successful commercialization of electrochemical H2O2 production requires cathode catalysts with high activity, selectivity and stability. In this Perspective, we highlight our current understanding of the factors that control the cathode performance. We review the influence of catalyst material, electrolyte and the structure of the interface at the mesoscopic scale. We provide original theoretical data on the role of the geometry of the active site and its influence on activity and selectivity. We have also conducted a series of original experiments on (i) the effect of pH on H2O2 production on glassy carbon, pure metals, and metal-mercury alloys, and (ii) the influence of cell geometry and mass transport in liquid half-cells in comparison to membrane electrode assemblies.

“…Metal impurities can influence the ORR even when present at very low concentrations, causing controversy on the nature of certain carbon-based catalysts [29]. Numerous reports show that the presence of transition metals, such as Fe [39,40] and Co [9,41] plays a strong role. Even concentrations in the range of hundreds or even tens of ppm can influence their electrocatalytic properties [42,43].…”

“…Among these, SACs with a MÀ NÀ C structure are the most popular [76,77]. Theoretical studies based on DFT calculations [78,79] have shown that the binding free energy of oxygen intermediates on CoÀ NÀ C places it near the top of the volcano plot of H 2 O 2 production, making it an excellent H 2 O 2 catalyst, whereas MnÀ NÀ C and FeÀ NÀ C bind the intermediates too strongly, making them effective H 2 O producers instead.…”

Single-atom catalysts (SACs) have been attracting extensive interest in the electrocatalytic production of hydrogen peroxide by oxygen reduction reaction (ORR). This is due to the maximal efficiency of atom utilization and intimate interaction of the metal centers with the supporting matrix that may be exploited for deliberate manipulation of the electrocatalytic activity and selectiv-ity, in comparison with the conventional nanoparticle counterparts. Herein, we summarize recent progress of the design and engineering of SACs towards ORR for H 2 O 2 generation, based on both noble and non-noble metals. We conclude the review with a perspective highlighting the promises and challenges involved in future research.
