Creating High-Number Defect Sites through a Bimetal Approach in Metal-Organic Frameworks for Boosting Trace SO 2 Removal.

Herein, we represent a bimetallic approach to enhance the defect number, leading to eight defect sites per node in a metal-organic framework, showing both a higher SO 2 adsorption capacity and higher SO 2 /CO 2 selectivity. The results can be further strongly supported by density functional theory calculations.
