Gas Sensing Performance of Composite Materials Using ...

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 ...

The Titano-Porphyrin doped pillared graphene as a novel ...

The aim of this study is to investigate and improvement of the CO gas sensing capacity of pure and Titano-Porphyrin doped pillared graphene (Ti-PIPG) using DFT calculations at B3LYP/6-31G (d) level of theory. To this end, a pillared graphene (PG) containing two parallel graphene sheets with four vertical (6,0) single walled carbon nanotubes as holders was selected. First, the effects of ...

Chemical crosstalk between heated gas microsensor elements ...

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 …

Nano-crystalline Cu-doped ZnO thin film gas sensor for CO ...

A Cu-doped ZnO (CZO) film was prepared on a glass substrate by co-sputtering using ZnO and Cu targets. The CZO film possessed a columnar structure consisting of small crystals with an average grain size of around 5. nm.. The CO-sensing properties of the CZO film were tested at operating temperatures of 150, 300, 350 and 400 ° was found that CZO-based sensor exhibited the highest ...
