Integrating Humidity‐Resistant and Colorimetric COF‐on‐MOF Sensors with Artificial Intelligence Assisted Data Analysis for Visualization of Volatile Organic Compounds Sensing

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 31, 2025

Abstract Direct visualization and monitoring of volatile organic compounds (VOCs) sensing processes via portable colorimetric sensors are highly desired but challenging targets. The key challenge resides in the development efficient systems with high sensitivity, selectivity, humidity resistance, profuse color change. Herein, a strategy is reported for direct VOCs by mimicking human olfactory function integrating COF‐on‐MOF artificial intelligence (AI)‐assisted data analysis techniques. Dye@Zeolitic Imidazolate Framework@Covalent Organic Framework (Dye@ZIF‐8@COF) sensor takes advantage porous structure MOF core hydrophobic nature COF shell, enabling sensitive trace number VOCs. Dye@ZIF‐8@COF exhibits exceptional sensitivity to at sub‐parts per million levels demonstrates excellent resistance (under 20–90% relative humidity), showing great promise practical applications. Importantly, AI‐assisted information fusion perceptual greatly promote accuracy processes, classification seven stages matcha drying superior 95.74%.

Atomic Ru Species Driven SnO₂-Based Sensor for Highly Sensitive and Selective Detection of H₂S in the ppb-Level

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 12, 2025

Timely and accurate detection of H2S is crucial for preventing serious health issues in both humans livestock upon exposure. However, metal-oxide-based sensors often suffer from mediocre sensitivity, poor selectivity, or long response/recovery time. Here, an atomic Ru species-driven SnO2-based sensor fabricated to realize highly sensitive selective at the parts per billion level as low 100 ppb. The shows a high sensing response (Rair/Rgas = 310.1) ultrafast time (less than 1 s) 20 ppm operating temperature 160 °C. Operando SR-FTIR spectroscopic characterizations DFT calculations prove that superior properties can be mainly attributed driven effect species on formation surface-adsorbed oxygen surface SnO2, which provides more active sites enhances performance SnO2 H2S. Furthermore, lab-made wireless portable monitoring system developed rapidly detect early warning, suggesting potential application system. This work novel approach fabricating gas by metal loaded metal-oxide semiconductors.
