For traditional cycloaddition reaction between CO 2 and epoxide, high temperature and high pressure are usually needed. In this work, we introduce Lewis acid Bi atom into the porphyrin ring of a metal–organic framework (MOF) structure (PCN-224) to facilitate the ring-opening of propylene oxide. In addition, light is introduced into the reaction, which enables the reaction to occur at ambient conditions (room temperature and 1 atm). Further investigations suggest that light plays an essential role in improving the efficiency, which activates the stable CO 2 molecule and lowers the energy barrier of the following cycloaddition reaction. This work provides a cost-effective and efficient approach to carry out the CO 2 cycloaddition reaction under ambient conditions.
