This study engineered a superacidic interface with pronounced polar electric field within the amine-water system by inducing hydrogen bond charge transfer in interfacial water via inverted microdroplets (microbubbles), thereby stabilizing protons layer. mechanism enabled continuous alkaline release of hindered amines (AMP-MIS), enhancing CO2 absorption load capacity and reducing regeneration energy consumption. Nuclear magnetic resonance potentiometric titration elucidated product distribution, while Raman spectroscopy, pH analysis, conductivity measurements confirmed proton stabilization. Theoretical calculations provided insights into reaction mechanism. Pilot-scale testing revealed AMP-MIS achieved 74.2% increase cyclic capacity, surpassing conventional 30 wt % MEA system, reduced from 3.667 GJ/t to 1.885 CO2. innovative strategy offers valuable guidance for advancing amine-based decarbonization technologies carbon emissions power industry, representing pivotal step toward neutrality.
