Investigating low-cost and highly active electrocatalysts for oxygen reduction reactions (ORR) is of crucial importance for energy conversion and storage devices. Herein, we design and prepare mesoporous carbon supported nitrogen-doped carbon by pyrolysis of polyaniline coated on CMK-3. This electrocatalyst exhibits excellent performance towards ORR in alkaline media. The optimized nitrogen-doped mesoporous electrocatalyst show an onset potential (E ) of 0.95 V (versus reversible hydrogen electrode (RHE)) and half-wave potential (E ) of 0.83 V (versus RHE) in 0.1 M KOH. Furthermore, the as-prepared catalyst presents superior durability and methanol tolerance compared to commercial Pt/C indicating its potential applications in fuel cells and metal-air batteries.
研究用于氧还原反应（ORR）的低成本、高活性电催化剂对于能量转换和存储设备至关重要。在此，我们通过在 CMK-3 上涂覆的聚苯胺的热解来设计和制备介孔碳负载的氮掺杂碳。该电催化剂在碱性介质中对 ORR 表现出优异的性能。优化的氮掺杂介孔电催化剂在 0.1 M KOH 中表现出 0.95 V（相对于可逆氢电极（RHE））的起始电位（E ）和 0.83 V（相对于 RHE）的半波电位（E ）。此外，与商业 Pt/C 相比，所制备的催化剂表现出优异的耐久性和甲醇耐受性，表明其在燃料电池和金属-空气电池中的潜在应用。
