Abstract Ensuring drinking water safety remains a critical challenge, particularly when treating complex sources, due to secondary pollution caused by active chemical additives. Herein, novel CO 2 ‐responsive smart wood scaffold that leverages non‐toxic activation is developed achieve highly efficient removal of carcinogenic natural organic matter (NOM) and broad‐spectrum microbial disinfection without requiring additional agents. Unlike conventional purification techniques face safety‐efficacy trade‐off, the multi‐stage offers exceptional tunability in NOM abatement across diverse environmental conditions, including variable chemistry, composition, high salinity, real‐world sources. The purified meets stringent standards (e.g., UV 254 reduction, dissolved carbon removal, bacterial elimination). It found adsorption mainly originates from strong stable ‐triggered cation−π interaction between surface aromatic groups, as revealed via high‐resolution mass spectrometry direct intermolecular force measurements. This ecofriendly contamination‐free strategy provides transformative approach overcoming challenges purification, offering scalable sustainable platform for applications beyond.
