武汉工程大学杨欢团队近日研究了用于工业级乙二醇氧化的生物碳约束双金属FeCo金属-有机框架正交纳米片阵列。这一研究成果于2025年5月27日发表在《结构化学》上。

乙二醇氧化反应（EGOR）对于解决聚对苯二甲酸乙二醇酯（PET）产量增加造成的环境问题非常重要。金属有机骨架（MOF）具有优异的稳定性、高比表面积和优异的催化性能，可以通过EGOR和析氢反应（HER）将PET转化为有价值的产品。 

研究组采用微生物模板策略制备碳球负载的正交纳米片双金属MOF催化剂。对于EGOR、HER和EGOR//HER，在100mA cm^-2的电流密度下，制备的催化剂分别只需要1.62 V、357 mV和1.83 V。更重要的是，它可以在500mA cm^-2的电流密度下稳定运行至少160小时。

双金属MOF的高比表面积和酵母碳壳的协同作用增加了固有活性位点与*OH和EG之间的接触面积，从而提高了EGOR和HER的催化活性和稳定性。这项工作提供了一种构建具有高效HER//EGOR性能的双金属正交电催化剂的新策略，这对实现可持续的能量转换和环境净化具有重要意义。

Abstract: Ethylene glycol oxidation reaction (EGOR) is important to address the environmental issues caused by the increasing production of polyethylene terephthalate (PET). Metal organic frameworks (MOFs) with superior stability, high specific surface area and excellent catalytic performance, can convert PET into valuable products through EGOR and hydrogen evolution reaction (HER). Herein, a microbial template strategy was adopted to prepare carbon sphere-supported orthogonal nanosheet bimetallic MOF catalysts. The prepared catalyst needs only 1.62 V, 357 mV, and 1.83 V at a current density of 100 mA cm-2 for EGOR, HER, and EGOR//HER, respectively. More importantly, it can stably perform for at least 160 h at a current density of 500 mA cm-2. The high specific surface area of the bimetallic MOF and the synergistic effect of the yeast carbon shell increase the contact area between the intrinsic active sites and *OH and EG, thus improving the EGOR and HER catalytic activity and stability. This work provides a novel strategy to construct bimetallic orthogonal electrocatalysts with efficient HER//EGOR performance, which is of great significance for achieving sustainable energy conversion and environmental purification.
