Enhanced methane sensing performance of NiO decorated ...

· The methane sensing performances of the NiO/In 2 O 3 nanocomposites were compared with the pure In 2 O 3, and the results indicated that the decorating of NiO significant enhanced the sensing capability. The response value of the NiO/In 2 O 3 nanocomposites toward 500 ppm CH 4 was ∼, which was nearly times higher than that of pure In 2 O 3 at 120 °C. In addition, the …

State-of-the-art of methane sensing materials: A review ...

· In the presence of a background of significant O 2 content such as methane sensing in air, the mechanism is typically explained through interactions between methane and oxygen molecules chemisorbed on the surface of a semiconductor sensing material. In the case of n-type semiconducting metal oxides, adsorbed oxygen species will capture electrons from the surface of the sensing layer, …

ACP - Remote sensing of methane leakage from natural gas ...

For two of the world's largest natural gas fields, Galkynysh and Dauletabad in Turkmenistan, we find collective methane emissions of ± Mt yr −1, which corresponds to a leakage rate of ± %, suggesting that the Turkmen energy industry is not employing methane emission avoidance strategies and technologies as successfully as those currently widely used in the United States. The leakage …

Remote Detection of Methane by Infrared Spectrometry for ...

The total length of natural gas pipelines in Germany exceeds 350,000 km. Currently, inspections are performed using hand-held sensors such as flame ionization detectors. Moreover, transmission pipelines are inspected visually from helicopters. In this work, remote detection of methane by passive Fourier-transform infrared (FTIR) spectrometry for pipeline surveillance is investigated. The study focuses on fast measurements in order to enable methane detection …

Methane sensing inside anti-resonant hollow-core fiber in ...

· Anti-resonant hollow-core silica fiber is used to demonstrate near- and mid-infrared laser absorption spectroscopy of methane. Molecular transitions near 6057 cm-1 (~1651 nm) and at cm-1 (~3270 nm) are targeted. Distributed feedback laser diode and interband cascade lasers are used as tunable laser sources. Detection of methane in ambient air is demonstrated using this mid-infrared …

Gas Sensors Methane -

Methane is a gas produced by a group of colonic anaerobes. All methane produced by human beings is a metabolic product of intestinal bacteria, and about 50% of it is excreted. Methane is also found below ground and under the sea floor. It is emitted during production and transport of coal, natural gas, and oil, as well as from lifestock. Methane makes up roughly 10% of Greenhouse Gas ...

A chemiresistive methane sensor

Methane sensing using SWCNTs is still at an early stage, however, owing to the difficulty of obtaining a selective response to the nonpolar and inert CH 4 molecule via traditional selector – analyte interaction strategies such as adsorption (22, 23), swelling (24, 25), receptor/guest interactions (26–28), or chemical reaction (29). For example, Star et al. constructed gas sensor arrays ...
