Bifunctional catalysts for one-pot CO2 conversion into value-added chemicals

Carbon dioxide (CO2) is not only a major greenhouse gas but also an abundant C1 feedstock for producing high-value cyclic carbonates used in batteries and polymers. Typically, the direct one-pot conversion of alkenes and CO2 requires complex multi-component catalytic systems. This research focuses on the development of single-component bifunctional catalysts (Co-mSiO2 @[Py-R][X]) by modifying mesoporous silica with cobalt centers and pyridinium-based ionic liquids. This design integrates redox-active sites and nucleophiles into a single robust framework. The integrated catalyst effectively overcomes diffusion limitations owing to its mesoporous structure, enabling the reaction to proceed under mild conditions. The system demonstrates high selectivity and excellent recyclability, offering a practical and sustainable platform for CO2 valorization in chemical manufacturing.
