2 sensors are less pronounced than in the case of CO sensing. A less than 1 % effect occurs for methanol sensing and the largest effect for H 2 sensing was an apparent concentration decrease of ≈4 % when heating 15 neighboring devices in 10 µmole/mole (10 ppm) of the analyte. On the bare SnO 2 devices, we observe an apparent increase in concentration of methanol and H 2 of ≈5 % and ≈15 ...

20/04/2021· Saadi et al. investigated the NO 2 sensing mechanism on the WO 3 surface, and they observed that the 001 facet of WO 3 was more stable and suitable for NO 2 sensing. Furthermore, they discussed the significance of oxygen vacancies on metal oxide surfaces and their role in the dissociation of NO 2 molecules for the generation of more vacancies, and thus more active sites for the target …

sensitivity for CO sensing of the nanoparticular SnO2 sensors at an operating temperature of 450°C. It is well known that the evolution of the conductance of the sensitive layer is largely modified by doping. A study carried out to measure the influence of humidity demonstrates that if un-doped sensors show a variation of same sign but less important than in dry air, doped sensors display a ...
The CO sensing mechanism of PANI is not yet clear, but two plausible explanations have been pro-posed. One is that the CO (-CO+) can naturally interact with undoped nitrogen atoms in the PANI chains to produce a polaron (-NH.+-) such that the conversion induces a higher density of charge carriers, thus increasing the conductance. Another possibility is that oxidation occurs at the grain sur ...
