Abstract

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.
