Herein, Fe-phthalocyanine-based conjugated microporous polymer (Fe-Phth-CMP) coated metal organic framework (ZIF-67) composites, namely Fe-Phth-CMP@ZIF-67, were facilely prepared via a rational and effective solid-phase synthesis method, in which, ZIF-67 worked as both precursors and templates. Upon carbonization, these special composites, with controllable morphology similar to ZIF-67 and adjustable Fe/Co molar ratio, can be further converted into N-doped porous carbons embedded with highly dispersed FeCo alloy and Fe/Co–N active sites. The optimal catalyst (denoted as P₂Z₃-900, prepared in a mass ratio of m_POP: m_ZIF = 2 : 3) features hierarchical pore structure which could significantly enhance the mass transfer efficiency and promotes the exposure of active sites, leading to high ORR and OER activity in alkaline conditions, simultaneously. For example, P₂Z₃-900 presents a half-wave potential (E_1/2) of 0.81 V (vs RHE) with a diffusion-limited current density of 5.56 mA cm⁻², comparable to commercial Pt/C (0.83 V and 5.60 mA cm⁻²), but much better than other prepared control samples. The Eonset of OER at 10 mA cm⁻² reaches 1.60 V with a small Tafel slope of 57 mV dec⁻¹. More importantly, the current synthetic method offers a rational strategy to structure-, morphology-, and element composition-controlled porous carbons, thereby finely regulating the property for efficient catalysis.

在此，通过合理有效的固相，容易地制备了Fe-酞菁基共轭微孔聚合物（Fe-Phth-CMP）包覆的金属有机骨架（ZIF-67）复合材料，即Fe-Phth-CMP @ ZIF-67。合成方法，其中ZIF-67既是前体又是模板。碳化后，这些特殊的复合物具有类似于ZIF-67的可控形态和可调节的Fe / Co摩尔比，可以进一步转化为嵌入了高度分散的FeCo合金和Fe / Co-N活性位点的N掺杂多孔碳。最佳催化剂（表示为P ₂ Z ₃ -900，以m _POP：m _ZIF的质量比制备= 2：3）具有分级的孔结构，可显着提高传质效率并促进活性位点的暴露，同时导致碱性条件下的高ORR和OER活性。例如，P ₂ Z ₃ -900的半波电势（E _1/2）为0.81 V（vs RHE），扩散限制电流密度为5.56 mA cm ^-2，可与商用Pt / C（0.83）相比V和5.60 mA cm ^-2），但比其他制备的对照样品好得多。OER在10 mA cm ^-2时的Eonset达到1.60 V，Tafel斜率为57 mV dec ^-1。更重要的是，当前的合成方法为控制结构，形态和元素组成控制的多孔碳提供了合理的策略，从而精细地调节了性能以进行有效催化。
