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.

As an organic compound, it has significant application value. Triethylamine (TEA) is widely used in chemical, pharmaceutical, pesticide, dye, and other fields. However, its toxicity makes impact on the environment human health undeniable. Therefore, developing low-power, high response, ultraselectivity, stability sensors for detecting this toxic gas crucial healthcare environmental monitoring. In work, we synthesized Ru-doped ZnO (Rux%ZnO) nanoparticles, which exhibited multiple enhanced sensing performance TEA detection. Typically, response value (Ra/Rg) of Ru0.05%ZnO sensor to 50 ppm at 260 °C as 2907, nearly 15 times higher than pristine ZnO. addition, compared with sensor, optimal operating temperature also been reduced by 80 °C. Exceptionally, under condition a relative humidity 85% (set 25 °C), Ra/Rg Ru0.05ZnO 10 still up 126. Finally, mechanism Rux%ZnO was explored.
