【Abstract】 Using tricarboxylic acid ligand containing hydroxyl functional group and zinc nitrate as raw materials,a new zinc metal organic framework was synthesized by solvothermal method with N,N-dimethylformamide as solvent.The effects of the amount of metal salt,carboxylic acid ligand and organic solvent,reaction temperature and reaction time on the reaction were discussed.The optimal synthetic reaction conditions were determined.The molar ratio of metal salt to carboxylic acid ligand was 1.5∶1.The molar ratio of organic solvent to carboxylic acid ligand was 300∶1.The reaction temperature was 110 ℃,and the reaction time was 48 h.Under these conditions,metal organic framework materials with high relative crystallinity can be synthesized.更多还原
