Solid-liquid biphasic absorbents are a promising solution for overcoming the high-energy consumption challenge faced by liquid amine-based CO2 capture technologies. However, their practical applications often hindered difficulties in separating viscous solid-phase products. This study introduces novel nonaqueous absorbent system (PD/PZ/NMP) composed of 4-amino-1-methylpiperidine (PD), piperazine (PZ), and N-methyl-2-pyrrolidone (NMP), engineered to produce easily separable powdery The PD/PZ/NMP achieves loading 0.86 mol-CO2/mol-amine, with 91% concentrated solid phase. It demonstrates excellent cyclic stability, maintaining regeneration efficiency after five cycles, reduces energy 52% compared conventional monoethanolamine absorbent. Remarkably, PZ plays crucial role regulating crystal composition products, transforming them from state crystalline powder. Characterization density functional theory analysis explain crystal-phase regulation mechanism: PD absorbs form zwitterions (PDH+COO-), affording forms protonated amines (PZH+) monocarbamates (PZCOO-), which interact PDH+COO- via hydrogen bonding These findings demonstrate efficacy provide robust theoretical framework fabricating solid-liquid tailored applications.
