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.
Natural laccase exhibits a broad substrate and only water is a by-product, making it an environmentally friendly enzyme. It has good application prospects in food engineering, paper making, textile, environmental...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
