“…This study paved the way for using metal-enriched plants for electrochemical energy conversion and storage applications to prepare porous carbon materials. Lei et al 32 used a boron-and oxygen-rich polymer network as the precursor and prepared low-cost boron-oxygen co-doped porous carbon electrocatalysts by one-step pyrolysis for the oxygen reduction reaction. Boron-oxygen co-doped carbon catalysts had high ORR electrocatalytic activity, and were comparable to Pt/C catalysts.…”

“…The results showed that boron doping was a promising method for preparing efficient ORR catalysts. 32 Zheng et al 33 based on first-principles calculations, theoretically discussed the application potential of BC 3 and NC 3 nanosheets as suitable cathodic electrocatalysts. The results showed that BC 3 and NC 3 nanosheets could reduce the overpotential and facilitate the ORR process.…”

“…However, the limited reserve, high cost, and vulnerable stability of Pt‐based catalysts have largely hindered the widespread utilization of fuel cells . In this context, many efforts have been made toward the development of metal‐free catalysts in recent years . Of these, N‐doped carbon‐based materials hold greater promise compared with their counterparts owing to their high activity, good durability, and low cost .…”

N-doped carbon materials represent promising metal-free electrocatalysts for the oxygen reduction reaction (ORR), the cathode reaction in fuel cells, metal-air batteries, and so on. A challenge for optimizing the ORR catalytic activities of these electrocatalysts is to tune their local structures and chemical compositions in a rational and controlled way that can achieve the synergistic function of each factor. Herein, we report a tandem synthetic strategy that integrates multiple contributing factors into an N-doped carbon. With an N-containing MOF (ZIF-8) as the precursor, carbonization at higher temperatures leads to a higher degree of graphitization. Subsequent NH etching of this highly graphitic carbon enabled the introduction of a higher content of pyridine-N sites and higher porosity. By optimizing these three factors, the resultant carbon materials displayed ORR activity that was far superior to that of carbon derived from a one-step pyrolysis. The onset potential of 0.955 V versus a reversible hydrogen electrode (RHE) and the half-wave potential of 0.835 V versus RHE are among the top ranks of metal-free ORR catalysts and are comparable to commercial Pt/C (20 wt %) catalysts. Kinetic studies revealed lower H O yields, higher electron-transfer numbers, and lower Tafel slopes for these carbon materials compared with that derived from a one-step carbonization. These findings verify the effectiveness of this tandem synthetic strategy to enhance the ORR activity of N-doped carbon materials.

“…8−10 Therefore, the development of a new type of ORR catalysts with low-cost and high catalytic performance as a substitute for Pt-based catalysts has received considerable attention. 11 Heteroatoms (e.g., B, 12 N, 13 S, 14 and P 15 ) doping carbon materials has been considered as an effective way to tune the surface wettability and electronic conductivity of carbon materials. This is one of the ways to and thus can improve the electrocatalytic activity for ORR.…”

Development of efficient catalysts with low cost for the oxygen reduction reaction (ORR) plays an important role in the commercialization of fuel cells. Herein, we reported a facile method to synthesize Fe–N co-doped porous carbon (Fe–N/C) by using green media ionic liquids 1-butyl-3-methylimidazolium tetrachloridoferrate ([Bmim][FeCl4]) as precursor of C, N, and Fe, and spherical silica as a template through one-step pyrolysis. Electrochemical measurements show that Fe–N/C800 possesses excellent ORR catalytic activity. The onset potential and half-wave potential are 0.964 and 0.821 V, respectively, which is close to those on the commercial Pt/C catalyst. Moreover, it exhibits better methanol tolerance and durability in comparison with the Pt/C catalyst. Good performance of Fe–N/C800 in ORR is attributed to its abundant porous structure, large BET surface area, and the synergism of Fe and N dopants.
