U-Co Bimetallic-Organic Framework Showing a Helical 1D Pore Decorated by Abundant -CH3 Groups: Robust Nature under Acid, Base, and Water for High-Performance SO2 Removal.

Constructing robust adsorbents for SO2 removal remains a challenging issue. Herein, a U-Co bimetallic-organic framework, namely, ECUT-123, showing a helical 1D pore decorated by abundant -CH3 groups, enables ultrahigh stability under acid, base, and water. This merit further supports its big potential for the removal of trace SO2.
