Liquid-based materials for air purification

Year: 2025

Type: article

Abstract: Enhancing air quality has garnered increasing global attention as a critical environmental issue, necessitating advanced purification technologies to address limitations of traditional solid-based systems, including rapid clogging and restricted dust-holding capacity. Liquid-based materials present a transformative approach, capitalizing on dynamic interfacial properties, defect-free architectures, and tunable functionality. This Flash Report systematically evaluates four innovative liquid-based systems: electrochemical liquid-based system (ELBS), liquid-gating topological gradient microfluidics (LGTGM), circulatory/respiratory-inspired air purification system (CAPS), and liquid-mediated system (LMS). These systems employ microbubble generation or core-shell fiber architectures to maximize gas-liquid contact area and mass transfer efficiency, while optimized solid-liquid interface design ensures robust system stability. Experimental results demonstrate superior performance, including near-100 % particle removal efficiency, high dust-holding capacity, and resistance to corrosion and clogging, providing a new strategy for air purification.
