Abstract

Abstract

En 中文
• UiO-66-(OH)₂ achieves 91 CO₂/N₂ IAST selectivity and 1.96 mmol g⁻¹ working capacity at 0.15 bar. • PSA-SPUR process theoretically enables both 100% CO₂ recovery/purity from 15% flue gas at moderate vacuum (≥0.15 bar). • Synergy between MOF adsorbent and process design drastically enhances the performance of CO2 capture PSA systems.
