SU-101: a Bi(III)-based metal–organic framework as an efficient heterogeneous catalyst for the CO2 cycloaddition reaction.

A non-porous version of SU-101 (herein n-SU-101) was evaluated for the CO₂ cycloaddition reaction. The findings revealed that open metal sites (Bi³⁺) are necessary for the reaction. n-SU-101 displays a high styrene oxide conversion of 96.6% under mild conditions (3 bar and 80 °C). The catalytic activity of n-SU-101 demonstrated its potential application for the cycloaddition of CO₂ using styrene oxide. [ABSTRACT FROM AUTHOR]
