摘　　要：以金属锌有机碳骨架MOF-5作为碳源,以双氰胺做为结构导向剂,通过高温氧化,制备出氧化锌掺杂多孔碳复合材料(ZnO@C)。采用X-射线粉末衍射、扫描电子显微镜、透射电子显微镜、N2吸附/脱附,拉曼光谱对样品的结构和形貌进行表征。结果表明:ZnO纳米粒子分布于无定形多孔碳的孔道中,粒径约为50 nm。复合材料ZnO@C多孔疏松的结构及较高的比表面积和孔体积为小分子自组装提供了理论依据。ZnO doped porous carbon composites(ZnO@C)were prepared,in this work,by using MOF-5 as the carbon source,dicyandiamide as the template under high temperature oxidation.The structure and morphology of the products were characterized by XRD,SEM,TEM,N2 adsorption/desorption and Raman spectroscopy.Our results show that the ZnO nanoparticles with an average diameter of 50 nm distribute in the channel of amorphous porous carbon.These porous structures of the ZnO@C with high surface areas and pore volumes provide a solid basis for the self-assembly of small molecules.
