Integration of MnO_x into the carbon matrix proves a viable strategy to improve the electrochemical performance of MnO_x materials. Mn₃O₄ nanoparticle‐decorated N‐doped carbon composites (Mn₃O₄@N‐doped carbon) were facilely prepared from a non‐porous eight‐fold interpenetrated Zn^II‐based MOF, which involves first synthesis of bimetallic Mn/Zn‐MOF in one‐pot reaction followed by direct pyrolysis at 1000 °C. In 0.1 m KOH solution, the optimal Mn₃O₄@N‐doped carbon exhibits decent oxygen reduction activity with the onset potential (E_onset) of 0.94 V (vs. RHE) and half‐wave potential (E_1/2) of 0.81 V (vs. RHE), excellent methanol tolerance as well as good durability.

高效还原氧气，轻松合成MOF衍生的Mn3O4 @ N掺杂碳

MnO _x整合到碳基质中证明了一种可行的策略，可以改善MnO _x材料的电化学性能。Mn ₃ O ₄纳米颗粒修饰的N掺杂碳复合材料（Mn ₃ O ₄ @N掺杂碳）是由无孔的八倍互穿的Zn ^II基MOF轻松制备的，该方法涉及首先合成双金属Mn / Zn。 -MOF在单锅反应中，然后在1000°C下直接热解。在0.1 m KOH溶液中，最佳的Mn ₃ O ₄ @N掺杂碳具有良好的氧还原活性，且具有起始电位（E_起始）为0.94 V（vs. RHE），半波电势（E _1/2）为0.81 V（vs. RHE），优异的甲醇耐受性和耐久性。
