Abstract
Abstract Due to the serious ecological problems caused by the high CO 2 content in the atmosphere, reducing atmospheric CO 2 has attracted widespread attention from academia and governments. Among the many ways to mitigate CO 2 concentration, the capture and comprehensive utilization of CO 2 through chemical methods have obvious advantages, whose key is to develop suitable adsorbents and catalysts. Frustrated Lewis pairs (FLPs) are known to bind CO 2 through the interaction between unquenched Lewis acid sites/Lewis base sites with the O/C of CO 2 , simultaneously achieving CO 2 capture and activation, which render FLP better potential for CO 2 utilization. However, how to construct efficient FLP targeted for CO 2 utilization and the mechanism of CO 2 activation have not been systematically reported. This review firstly provides a comprehensive summary of the recent advances in the field of CO 2 capture, activation, and transformation with the help of FLP, including the construction of homogeneous and heterogeneous FLPs, their interaction with CO 2 , reaction activity, and mechanism study. We also illustrated the challenges and opportunities faced in this field to shed light on the prospective research.
