中文摘要：

以合成的双金属配位聚合物Co（MAA）2/Ag（Ⅰ）纳米带为前驱体,制备了一维Ag@Co3O4纳米复合催化材料.采用傅里叶变换红外光谱（FTIR）、核磁共振氢谱（1H NMR）、粉末X射线衍射分析（XRD）、扫描电子显微镜（SEM）及透射电子显微镜（TEM）等方法对其结构进行了表征,结果表明,Ag纳米晶体和Co3O4纳米晶体均匀分布在Ag@Co3O4纳米带上.采用紫外-可见吸收光谱（UV-Vis）等方法考察了Ag@Co3O4纳米复合材料在亚甲基蓝（MB）染料还原反应中的催化性能,发现其具有良好的催化活性、循环稳定性及磁分离能力.

英文摘要：

1D,magnetic Ag@Co3O4 nanocomposite catalysts were prepared using a synthesized precursor of bimetallic coordination polymers Co（ MAA）2/ Ag（ Ⅰ） nanoribbon. The structure of the obtained material was characterized by Fourier transform infrared spectroscopy（ FTIR）, proton nuclear magnetic resonance（-1H NMR）,powder X-ray diffraction（ XRD）,scanning electron microscopy（ SEM） and transmission electron microscope（ TEM）. The results suggested that both the Ag and Co3O4 nanocrystals distributed uniformly in the entire Ag@Co3O4 nanoribbon. Meanwhile,UV-Visible absorption spectrum（ UV-Vis） was used to investigate the catalytic performance of Ag @Co3O4 nanocomposites towards the reduction of methyl blue（ MB） dye by sodium borohydride（ NaBH4）. The results show that the material has excellent catalytic activity,cyclic stability and magnetic separation ability.
