Abstract:
The exploration of efficient and low-consumption catalysts for carbon dioxide (CO2) conversion is desirable yet remains a great challenge. Herein, a novel catalyst composed of a hollow nitrogen-doped carbon framework (HNF) enriched with high-loading (9.8 wt %) atomically dispersed iron sites (defined as Fe) has been fabricated by a polymer-assisted strategy. As a result, Fe/HNF has an excellent performance on the cycloaddition reactions of CO2 with epoxides (the conversion >96%) under milder conditions because of its ultrahigh loading of atomically dispersed iron sites. This study not only provides an advanced catalyst for driving CO2 cycloaddition but also furnishes a novel perspective on the rational design of superior catalysts with high-loading active sites for diverse heterogeneous catalytic reactions.
