“…The above results conclusively signify that O-P/N-C900 can produce H 2 O 2 at high current densities at a large scale. In addition, very high faradaic efficiencies (FEs) of 85% to 95% were achieved in a potential range of 0.1 to 0.3 V, which is higher than most reported values, 40,54,[58][59][60][61][62][63][64][65][66] as compared in Fig. 4D.…”

“…In addition to the analogues in this work, the Co-F-CNT material also shows one of the highest H 2 O 2 yield rates among the recently reported catalysts under similar testing conditions (Figure 5F and Table S6). [35][36][37][38][39][40][41][42][43][44][45] Moreover, the chronoamperometric test of Co-F-CNT at À0.04 V vs. RHE confirmed its electrochemical stability (Figure 5G and S23). It is observed from the curve that within the whole testing period of 20 h, the concentration of H 2 O 2 produced increases linearly with the reaction time, indicating that the H 2 O 2 yield rate of the material is fairly constant and stable.…”

Producing hydrogen peroxide (H 2 O 2 ) via a two-electron oxygen reduction reaction (2 e À -ORR) is a promising alternative to the conventional anthraquinone process, because of its exceptional low-risk and distributed features. The low yield of H 2 O 2 on typical electrocatalysts, usually associated with limited and vulnerable catalytically active sites on their surface, has been the major restriction for improving the practical viability of this technology. Herein, we report an ultrafast microwave-based strategy for constructing distant coordination of Co single-atom sites with secondary fluorene heterodopants on carbon nanotubes, which successfully converts the 2 e À -ORR active centers from a single Co atom to multiple surrounding carbon atoms, increasing both the quantity and durability of active sites for 2 e À -ORR. Consequently, a high H 2 O 2 yield of up to 18.6 mol g À1 L À1 has been achieved, accompanied by a Faraday efficiency of 90%. Besides, an accumulative H 2 O 2 concentration of 5.2 g L À1 is obtained after 20 h electrocatalysis, showing the material's high stability and feasibility for practical applications. Density functional theory simulations confirm the optimal adsorption of *OOH on these carbon sites, providing very low kinetic barriers for 2 e À -ORR. Thus, this work provides a high-performance electrocatalyst for 2 e À -ORR, and more importantly strategy for promoting the performance of single-atom catalysts.

“…It is also worth mentioning that the mass transport ability which directly determines the prospects for industrial applications can be especially promoted by constructing the 3D open porous skeleton after assembling the TM-based catalysts with carbon species. [108,190] Another interesting point to note is that the performance of an electrocatalyst in 2e − ORR is influenced by its pore sizes. Mesopores are typically preferred as they facilitate mass transport and product release during 2e − ORR.…”

Non‐noble transition metal (TM)‐based compounds have recently become a focal point of extensive research interest as electrocatalysts for the two electron oxygen reduction (2e− ORR) process. To efficiently drive this reaction, these TM‐based electrocatalysts must bear unique physiochemical properties, which are strongly dependent on their phase structures. Consequently, adopting engineering strategies toward the phase structure has emerged as a cutting‐edge scientific pursuit, crucial for achieving high activity, selectivity, and stability in the electrocatalytic process. This comprehensive review addresses the intricate field of phase engineering applied to non‐noble TM‐based compounds for 2e− ORR. First, the connotation of phase engineering and fundamental concepts related to oxygen reduction kinetics and thermodynamics are succinctly elucidated. Subsequently, the focus shifts to a detailed discussion of various phase engineering approaches, including elemental doping, defect creation, heterostructure construction, coordination tuning, crystalline design, and polymorphic transformation to boost or revive the 2e− ORR performance (selectivity, activity, and stability) of TM‐based catalysts, accompanied by an insightful exploration of the phase‐performance correlation. Finally, the review proposes fresh perspectives on the current challenges and opportunities in this burgeoning field, together with several critical research directions for the future development of non‐noble TM‐based electrocatalysts.This article is protected by copyright.
