Abstract Solid acid catalysts (SACs) have attracted significant attention for their role in enhancing the carbon capture desorption process, primarily due to active sites. By employing a synergistic strategy involving anchoring and structural design, both catalytic activity durability of catalyst throughout process are optimized. The TiO 2 shell layer Mn CoO 4 @TiO /SO 2− (MC@TiO /S) effectively inhibits leaching species into solution, thereby enabling sustained high over ten cycles absorption–desorption testing. protonated groups (SO ) facilitates novel pathway proton transfer solution via proton‐coupled electron (PCET) effect, significantly reducing activation energy this step reaction kinetics. Consequently, CO regeneration capacity rate increase by 103% 111%, respectively, while consumption during decreases ≈44%. Additionally, environmental performance is evaluated using life cycle assessment (LCA), highlighting its sustainable potential future scale‐up applications. This study presents viable metal oxide solid materials facilitate efficient low‐energy solvent processes.

Chiral Lewis acid catalysts are widely used in organic synthesis due to their diverse applications. However, high acidity makes them susceptible deactivation by basic reagents and water. Here, we present a novel strategy for mitigating this using small molecules. By incorporating weakly coordinating anions into the secondary coordination sphere of metal center, designed highly reusable chiral complex. This complex exhibits excellent thermal stability allows use electron-poor nucleophiles reactions. Spectroscopic titration studies confirmed robustness optimized work provides valuable insights overcoming limitations acids environments, expanding potential chemical synthesis.
