Effect of Supported Transition Metal on CO Sensing ...

CO sensing properties of various transition metal oxide-loaded SnO2 sensors were investigated in a reducing atmosphere such as wet H2 gas. Among transition metal oxide-loaded SnO2 sensors used in the present study, 5wt%CuO-loaded SnO2 sensor exhibited the highest sensitivity to 1% CO in wet 50% H2 at around 150 °C, while it showed no sensitivity in dry 50% H2.

Carbon dioxide sensor - Wikipedia

CO 2 can be measured using photoacoustic spectroscopy. Concentration of CO 2 can be measured by subjecting a sample to pulses of electromagnetic energy (such as from a Distributed Feedback Laser) that is tuned specifically to the absorption wavelength of CO 2. With each pulse of energy, the CO 2 molecules within the sample will absorb and generate pressure waves via the photoacoustic effect ...

· CO 2 sensing in mammalian neuronal cells. From a physiological standpoint, some of the most important CO 2 sensors are those that control breathing in mammals. Changes in CO 2 and CO 2 /H + levels are sensed in special chemosensitive neurons located peripherally in the carotid body and centrally in the central nervous system. The peripheral carotid neurons detect arterial CO 2 and pH, …

· We demonstrate a room temperature sensing of CO gas (1–5 ppm) using high performance single Zn-doped In 2 O 3 nanowire field effect transistors (Zn–In 2 O 3 NW-FETs). Zn–In 2 O 3 nanowires were grown in a horizontal CVD furnace; single Zn–In 2 O 3 NW-FETs were fabricated using SiN x dielectric layer and bottom gate. Electrical measurements on the NW-FETs showed high …

Abstract AlGaN/GaN high electron mobility transistors (HEMTs) functionalized with ZnO nanorods were used for sensing CO in the concentration range of 50–500 ppm balanced with air at ambient and temperatures from 25 to 250 °C. An increase of the HEMT drain current was observed for exposure to the CO-containing ambient. The sensing limitation was improved from 100 ppm to 50 ppm by increasing ...
