Abstract
Conventional gas absorption systems require continuous liquid circulation, leading to high energy consumption, solvent loss through evaporation, and equipment corrosion. Although hydrogel beads were proposed to address this issue, liquid bridges formed between beads hinder their full utilization of interfacial area. Liquid marble, which is a droplet covered by hydrophobic solid particles, stabilizes the droplet to behave like individual solid material. In this study, we design a novel approach that utilizes spherical solvent-infused hydrogel marbles (SIHMs) to prevent solvent leakage and mechanical wear of the chamber. Crucially, the hydrophobic surface of the marbles suppresses the formation of interparticle liquid bridges, ensuring a maximized gas-liquid interfacial area even in a static environment. The presence of voids between the marbles enhances gas absorption efficiency. Additionally, with high compatibility of SIHMs, it can be customized with specific solvents to various target gases. When integrated with non-volatile solvents like ionic liquids, this system maintains long-term performance through repeated desorption cycles, offering a robust alternative to conventional fluid-based carbon capture and gas treatment processes.
