Copper Oxide/Carbon (CuO/C) nanocomposites were developed through the green method using the leaf extract of at room temperature. Here, the leaf extract serves as a capping agent, reducing agent and a source of carbon for the formation of nanocomposites. As we know, this is the first article on the synthesis of CuO/C nanocomposites using this leaf extract. The nanocomposites were prepared by mixing the copper sulphate pentahydrate solution with the plant extract under certain conditions. The synthesized material was characterized by XRD, UV-Visible, FTIR, FE SEM, EDS, XPS and TGA. The results revealed that the synthesized material is a composite of copper oxide and functionalized graphene-like carbon. The SEM images indicated that the CuO/C nanoflakes had an average thickness of 7-11nm. Further, the composites were examined for antifungal activity and antibacterial activity. The nanocomposites showed significant antibacterial activity against the pathogenic bacterial strains and and antifungal activity against the fungi and Also, the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal/Bactericidal Concentration (MFC/MBC) of the nanocomposites were determined against the fungus and the bacteria
氧化铜/碳（CuO/C）纳米复合材料是在室温下通过绿色方法利用[植物名称]的叶提取物制备而成。在此，叶提取物充当封端剂、还原剂以及形成纳米复合材料的碳源。如我们所知，这是第一篇关于使用这种叶提取物合成CuO/C纳米复合材料的文章。纳米复合材料是通过在特定条件下将五水硫酸铜溶液与植物提取物混合制备而成。合成材料通过X射线衍射（XRD）、紫外可见光谱（UV - Visible）、傅里叶变换红外光谱（FTIR）、场发射扫描电子显微镜（FE SEM）、能谱分析（EDS）、X射线光电子能谱（XPS）和热重分析（TGA）进行表征。结果表明，合成材料是氧化铜和功能化类石墨烯碳的复合材料。扫描电子显微镜图像表明，CuO/C纳米片的平均厚度为7 - 11纳米。此外，对复合材料进行了抗真菌活性和抗菌活性检测。纳米复合材料对致病细菌菌株[细菌名称1]和[细菌名称2]表现出显著的抗菌活性，对真菌[真菌名称1]和[真菌名称2]表现出抗真菌活性。此外，还测定了纳米复合材料对真菌[真菌名称1]和细菌[细菌名称1]的最小抑菌浓度（MIC）以及最小杀菌浓度（MFC/MBC）
