The invention discloses a method for synthesizing cyclic carbonate through heterogeneous catalysis. The method is characterized in that carbon dioxide and epoxide are used as raw materials, a super-crosslinking metalloporphyrin porous material is used as a multi-phase catalyst, quaternary onium salt is used as a catalyst promoter, so that high-efficiency high-selectivity catalyzed synthesis of the cyclic carbonate is realized under the conditions that the concentration of the carbon dioxide is 15 to 100 percent, the pressure is 0.1 to 3.0 MPa and the temperature is 25 to 100 DEG C. The method disclosed by the invention has the main advantages that the catalyst activity is high, the performance is stable, the preparation method is simple, the cost is low, recovery is easy, reaction conditions are mild, and no any solvent is required to be added; in addition, the carbon dioxide in industrial waste gas can be utilized as the raw material, the carbon dioxide can be catalytically converted into the cyclic carbonate under the conditions of normal temperature and normal pressure, and industrial application value is obtained.
