The invention provides a method for removing sulfur dioxide through a catalyst prepared from a metal organic framework material and belongs to the technical field of flue gas desulfurization. The method comprises the following steps: dissolving zinc nitrate hexahydrate and terephthalic acid into equal amount of N,N-dimethylformamide at the mol ratio of 2 to 1 under violent stirring; after the zinc nitrate hexahydrate and theterephthalic acid are dissolved, transferring the mixture into a reaction kettle with a polytetrafluoroethylene lining; putting the reaction kettle into a drying oven at 150-240 DEG C to react for 18-30 hours and then taking out the product; filtering and washing with the N,N-dimethylformamide; drying at 80 DEG C for one night to obtain the metal organic framework material MOF-5; carrying out vacuumizing treatment on the prepared metal organic framework material MOF-5 at 150-250 DEG C for 12-24 hours so that the vacuum degree is smaller than 10-3mmHg; and carrying out an SO2 removing perfo
