Abstract Trees, consisting of leaves, trunks, etc., efficiently eliminate gaseous pollutants and serve as an indispensable air purification system for Earth. In this study, lignin from trunks phytol leaves are co‐assembled into macroporous nanospheres with high efficiency scavenging reactive oxygen species (ROS) harmful gases, which integrated cigarette filters lung protection. The alkyl chains disrupt the π–π stacking in lignin, forming pore throats that expand 0 to 120 nm content increases. Consequently, higher levels anchored phytol, greater antioxidant capacity co‐assemblies. subsequently loaded filters, each gram porous nano‐lignin capable treating ≈100 standard cigarettes. ROS can reach up 97%, effectively removing gases like carbon monoxide formaldehyde, outperforming existing filters. a mouse model, containing these microscopic purifiers significantly suppressed inflammation provided notable tissue This study presents robust non‐covalent method is both straightforward efficient, enabling rapid application plant extracts highly effective sustainable filter materials.

Efficient personal protection has emerged as a crucial approach for reducing pulmonary injury induced by particulate matter (PM). However, current protective equipments usually lack essential biosafety concerns and fail to own adsorbing/antioxidant/antibacterial function together, making it challenge develop an integrated platform with the above characteristics. Herein, facile oxygen-free hydrothermal strategy is proposed synthesize new copper-based metal-organic frameworks, Cu-HHTPs, (HHTP: 2,3,6,7,10,11-hexahydroxytriphenylene), great activity high biosafety. The Cu-HHTPs can serve efficient additive incorporated various fabrics including cellulose acetate (CA) membrane achieve novel fabric composites, such CA@Cu-HHTPs, ideal scavenging outcome main components of PM. Evidenced animal experiments, CA@Cu-HHTPs highly mitigate PM-induced adverse effects via adsorbing PM, ROS, killing bacteria, leading significant reduction in lung permeability, inflammation oxidative stress, infection. Last but not least, two-week exposure exhibits no obvious damage toward animals examining their long-term toxicity. Collectively, this study only highlights potential attractive additives preparation also lays out concept development new-generation multifunctional equipment against
