Metal–organic frameworks (MOFs) have been considered as versatile materials for applications in energy fields. For improving reactivity, structural collapse will cut the important advantage of frameworks and hinder the exposure to reactive centers. Herein, we constructed rich structural vacancies in MOFs by the thermal decomposition of specific functional groups, which will not only expose more reactive sites and modulate the electronic structure on the premise of maintaining the frame structure but also benefit in situ derivations to form uniformly along the defect interface. After integrating metal phosphides with defective MOFs, the electrocatalyst shows a low overpotential of 295 mV at 10 mA cm⁻² and long-term OER stability, both of which are primarily attributed to the enlarged electrochemically active surface area and accelerated charge-transfer rate in the unique structure.

部分磷酸化促进有缺陷的CoP / MOF集成电催化剂的氧释放反应

金属有机框架（MOF）被认为是用于能源领域的通用材料。为了提高反应活性，结构塌陷将削弱构架的重要优势并阻碍其暴露于反应中心。在这里，我们通过特定官能团的热分解在MOF中构建了丰富的结构空位，这不仅会暴露更多的反应性位点并在保持框架结构的前提下调节电子结构，而且还有利于原位衍生物沿金属骨架均匀地形成。缺陷界面。在将金属磷化物与有缺陷的MOF结合后，电催化剂在10 mA cm ^-2时显示出295 mV的低过电势 以及长期的OER稳定性，这两者都主要归因于独特结构中扩大的电化学活性表面积和加速的电荷转移速率。
