The sluggish oxygen reduction reaction kinetics hinders the development fuel cells, which needs effective electrocatalyst with low cost and high efficiency to realize 4 e À reduction processes. To alternate commercial Pt/C, herein, hollow carbon nanocubes were successfully prepared and evaluated as oxygen reduction electrocatalyst. Benefit from the effective abundant nitrogen species and unique hollow architecture, the hollow carbon nanocubes exhibit favorable oxygen reduction electrochemical performance with onset potential of 0.94 V, half-wave potential of 0.82 V, and limited current density of 6.11 mA cm À 2 , which are comparable to those of Pt/C. Additionally, compared to Pt/C, the HC-800 shows expressively stability and methanol tolerance.

“…Recent advances have been made regarding the inuence of total N content and/or different N types (e.g., graphitic, pyridinic, and pyrrolic N) on ORR activity. [12][13][14][15][16][17][18][19][20] When located in the edge area of carbon frameworks, N-doped carbons containing only effective N species provide plentiful active sites for the catalysis of ORR. 21 However, conicting reports have been published with respect to the active site afforded by N species.…”

“…Therefore, catalysts must be used to boost the efficiency of the reduction process. There are several classes of catalysts proposed for hydrogen peroxide production, which include single atom metal catalysts, [13–17] noble metal nanoparticles or noble metal alloys, [18–24] transition‐metal oxides, phosphides or chalcogenides, [25–29] and metal‐free carbon‐based materials [29–40] . The lattermost class of materials has received a special attention owing to their low‐cost and diversified ways of production, favorable selectivity and good chemical stability [41–43] .…”

Carbon materials slightly doped with heteroatoms such as nitrogen (N‐RFC) or sulfur (S‐RFC) are investigated as active catalysts for the electrochemical bielectronic oxygen reduction reaction (ORR) to H2O2. Mesoporous carbons with wide, accessible pores were prepared by pyrolysis of a resorcinol‐formaldehyde resin using a PEO‐b‐PS block copolymer as a sacrificial templating agent and the nitrogen and sulfur doping were accomplished in a second thermal treatment employing 1,10‐phenanthroline and dibenzothiophene as nitrogen and sulfur precursors, respectively. The synthetic strategy allowed to obtain carbon materials with very high surface area and mesopore volume without any further physicochemical post treatment. Voltammetric rotating ring‐disk measurements in combination with potentiostatic and galvanostatic bulk electrolysis measurements in 0.5 m H2SO4 demonstrated a pronounced effect of heteroatom doping and mesopores volume on the catalytic activity and selectivity for H2O2. N‐RFC electrode was employed as electrode material in a 45 h electrolysis showing a constant H2O2 production of 298 mmol g−1 h−1 (millimoles of H2O2 divided by mass of catalyst and electrolysis time), with a faradic efficiency (FE) up to 61 % and without any clear evidence of degradation. The undoped carbon RFC showed a lower production rate (218 mmol g−1 h−1) but a higher FE of 76 %, while the performances drastically dropped when S‐RFC (production rate 11 mmol g−1 h−1 and FE=39 %) was used.
