Due to the unique microstructure and superior catalytic properties, organic‐inorganic hybrid materials attract extensive attention. Herein, we report a facile coprecipitation method for the fabrication of metalloporphyrin–metal phosphate salt hybrid spheres, and the cycloaddition of carbon dioxide with epoxides is employed as probe reaction to evaluate the catalytic performance of our as‐synthesized catalysts. The hybrid spheres composed of meso‐tetra‐(4‐N‐pyridyl) zinc porphyrin (ZnTPyP)–magnesium phosphate exhibited superior catalytic performance, and the conversion was much higher than that of individual ZnTPyP and magnesium phosphate, probably because of the acid‐base synergistic effect. Meanwhile, the spheres showed excellent stability during the circulation experiments as well as compatibility with a wide scope of substrates. This work provides a valuable approach for the preparation of novel and efficient heterogeneous catalytic composites.
