Dimethyl disulfide (DMDS) is a common odor pollutant with an extremely low olfactory threshold. Highly sensitive and selective detection of DMDS in ambient humid air background, by metal oxide semiconductor (MOS) sensors, highly desirable to address the increased public concern for health risk. However, it has still been critical challenge up now. Herein, p-type delafossite CuGaO2 proposed as promising sensing material owing its striking hydrophobicity (revealed water contact angle measurement) excellent partial catalytic oxidation properties (indicated mass spectroscopy). The present sensor shows response, satisfied humidity resistance performance long-term stability at relatively operation temperature 140 °C. An ultrahigh response 100 10 ppm limit 3.3 ppb could be achieved via pulsed modulation strategy. A smart system based on developed, which precisely monitor vapor air, even presence multiple interfering gases, demonstrating practical application capability MOS sensors environmental monitoring.

Recent advancements in photoactivated metal oxide (MOX) gas sensors and the application of plasmonic nanoparticles (NPs) hydrogen sensing have demonstrated significant potential enhancing sensor performance. Hydrogen, as a high‐energy, carbon‐free alternative to fossil fuels, requires reliable detection methods due its storage handling risks. Traditional MOX sensors, while cost‐effective versatile, face challenges such high operating temperatures limited selectivity. In this review, innovative photonic are explored overcome these limitations, focusing on photoactivation effects. Photonic activation improves sensitivity, response time, recovery time at room temperature, mitigating safety risks associated with high‐temperature operations. Additionally, integration NPs, made from gold, palladium, or other less noble metals, into enhances catalytic activity through localized surface plasmon resonance. also synergistic effects decoration enhancement covered, providing comprehensive overview current state possible future directions hydrogen‐sensing technology. These promise safer more efficient detection, crucial for expanding infrastructure role sustainable energy future.
