英文摘要Ammonia (NH3) sensors proposed for the simultaneous exhalation diagnosis, environmental pollution monitoring,and industrial leakage alarm require highflexibility, selectivity, stability, humidity tolerance, and wide-concentration-range detection;however, technical challenges still remain. Herein, twistable and water-tolerant paper-based sensors integrated over surgical maskshave been developed for NH3detection at room temperature, via decorating specially designed ternary nanocomposites (ternary-NCs) on the commercialfilter paper. The NCs consist of a multiwalled carbon nanotube framework with a polypyrrole nanolayerand are further loaded with Pt nanodots. Benefiting from the synergy effect of ternary components, the ternary-NCs exhibit anultrasensitive response to 5 ppb-60 v/v% NH3and present high selectivity confirmed by the theory calculations. Remarkably, thefilter-paper-based sensors possess outstanding stability against twisting 0-1080 degrees, along with excellent cuttability and foldability.Critically, such paper-based sensors can be integrated over surgical masks for simulated exhaled diagnosis and display superior watertolerance even being immersed in water for 24 h. Practically, the detecting accuracy of thefilter-paper-based sensor toward thesimulated exhaled NH3, environmental NH3pollution, and industrial NH3leakage is validated using ion chromatography.
