Addressing the high energy demand of amine-based carbon dioxide capture systems is crucial for achieving carbon neutrality. While enhancing energy efficiency with solid acid catalysts in amine regeneration is promising, developing more efficient catalysts remains a critical challenge. In this study, we introduce the innovative use of a robust, metal-free phthalocyanine as a catalyst to facilitate amine regeneration. Distinctively, phthalocyanine features a macrocyclic ring with an extensive π-conjugated system that functions as Lewis acid sites, diverging from conventional methods that rely on metal atoms for this role. Additionally, the nitrogen and hydrogen atoms on the macrocyclic ring act as Brönsted base sites and Brönsted acid sites, respectively. These sites collectively contribute to a significant acceleration in the CO2 desorption rate, achieving an increase of 1679% at approximately 67 ℃, which far surpasses the performance of previously investigated catalysts. Furthermore, phthalocyanine catalyzes the decomposition of carbamate and protonated monoethanolamine more efficiently than bicarbonate. This research lays the groundwork for next-generation catalysts in amine solvent regeneration of the carbon dioxide capture process.
