摘　　要：以不同溶剂尺度的酰胺类溶剂与甲酸混合溶液为溶剂模板,利用溶剂热法制备MOF-808。利用傅里叶变换红外光谱仪、扫描电镜、X-射线衍射仪和比表面积分析仪对样品进行性能表征。结果表明,溶剂尺度越小,MOF-808孔径越小,比表面积越大,N_2吸附性能越强。当甲酰胺/甲酸混合溶液作为溶剂模板时,MOF-808孔径最小,为1.19nm;比表面积最大,达到1625m^(2)/g。Amide solvents with different sizes were mixed with formic acid as solvent template to prepare MOF-808 by solvothermal method.The samples were characterized by fourier transform infrared spectroscopy tester,scanning electron microscope,X-ray diffractometry and specific surface area analyzer.The results shown that the smaller the solvent scale was,the larger the specific surface area of the MOF-808 sample and the stronger the adsorption performance will be.When the formamide/formic acid mixed solution was used as the solvent template,MOF-808 had the smallest aperture and its size was 1.19 nm,the specific surface area was the largest,reaching to 1625 m^(2)/g.
