Abstract: Catalysts and methods for making cyclic carbonates are disclosed. The catalyst may include at least one polymer quaternary ammonium salt, at least one metal halide and silica gel. The method of making the cyclic carbonates may include forming a mixture that includes the catalyst and an epoxide, and contacting the mixture with carbon dioxide in a reactor under conditions to form the propylene carbonate.
