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.

Per- and polyfluoroalkyl substances (PFAS) are emerging contaminants with increasing health concern due to their persistence, widespread presence, adverse effects. Short-chain PFAS, in particular, more challenging remove using conventional water treatment technologies. Hydrogel adsorbents have shown as a promising solution for short-chain PFAS removal, offering high adsorption capacity, rapid kinetics, tunable material properties. However, biofouling contamination which is easier happen on wet hydrogels compared process, could significantly reduce efficiency, shorten operational lifespan, increase overall costs. Antibiofouling modifications present viable strategy enhance hydrogel functionality drinking applications. This review summarizes recent advancements of antibiofouling removal applications through functional group modifications. Furthermore, it highlights gaps the current literature, particularly lack studies development evaluation both resistance capabilities
