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 1.19nm,the specific surface area was the largest,reaching to 1625m2/g.
