CO2 cycloaddition reactions are catalyzed by a variety of transition metal complexes, including homogeneous and heterogeneous catalysts. Homogeneous catalysts are typically based on Group 8-10 metals, such as rhodium, iridium, and nickel, and are oftenused in combination with a ligand system that help...

Studies on the reaction and conversion of CO2 to valuable products have made much progress in recent years, and the search for efficient catalysts is also expanding. Cycloaddition of CO2 to epoxides was carried out selectively using di-nuclear CuII, CoII and NiII complexes (C1, C2 and C3, ...
CO2 cycloaddition with epoxides to produce cyclic carbonates is a promising method for the resourceful use of CO2, but it remains a great challenge. Herein, one-dimensional [email protected] nanofibers ([email protected]) catalysts were synthesized for the first time by one-step pyrolysis of elect...
