为获得更高性能的电化学储能材料，兼具独特结构与优异特性的金属氧化物/氧化石墨烯复合材料体系受到广泛关注。本研究通过调控氧化石墨烯（GO）的引入量，构建金属有机框架（MOF）与GO的复合结构，并基于一步煅烧法成功制备了氮掺杂碳骨架支撑金属氧化物与GO的复合体系。电化学性能测试结果表明，当GO引入量为7 wt%时，复合材料的比电容可达642 F/g（1 A/g），5000次循环后容量保持率达93%，其优异的储锂性能源于GO对金属氧化物纳米颗粒的导电网络优化与结构稳定作用。该研究为高稳定性金属氧化物/碳基复合电极材料的理性设计提供了新思路。

In pursuit of more efficient and stable electrochemical energy storage materials, composite materials consisting of metal oxides and graphene oxide have garnered significant attention due to their unique structures and exceptional properties. Graphene oxide (GO), a two-dimensional material with an extremely high specific surface area and excellent conductivity, offers new possibilities for enhancing the electrochemical performance of metal oxides. In this work, we synthesized metal-organic framework (MOF) and GO composites with regulated amount of GO and successfully prepared composites of metal oxides supported by nitrogen-doped carbon frameworks and GO through a simple one-step calcination process. Through electrochemical tests, the optimal amount of GO was determined. This research will provide new insights and directions for designing and synthesizing metal oxide and graphene oxide composite materials with ideal electrochemical performance.
