Cover Feature: Rational Engineering of Pillar‐Layered Co‐MOFs Through the Hard‐Soft Acid–Base Principle: Elucidating Highly Robust Flue Gas Desulfurization Under Dynamic Dry and Humidity (ChemistryEurope 4/2026)

The Cover Feature depicts a robust pillar-layered MOF engineered for flue gas desulfurization. By leveraging HSAB theory to enhance structural stability and a pillared-layer strategy to expand pore volume, the framework incorporates specific Lewis basic sites. These introduced sites on the pillars act as selective traps for SO2 capture, enabling highly efficient sulfur removal from industrial emissions.
