A Novel Colorimetric H2S Measurement for Environmental and Oil and Gas Applications

Skates V.W.L., van Hal R.E.G., Schlumberger-Doll Research, US

This paper provides a novel colorimetric method to measure hydrogen sulfide in water, air, natural gas and oil. A bismuth ion based reagent reacts with sulfide to form bismuth sulfide nanoparticles, causing the solution to [...]

Nanocrystalline gold-based hydrogen sulfide (H2S) sensor from M13 bacteriophage template

Moon C.H., Zhang M., Yan Y., Myung N.V., Haberer E.D., University of California Riverside, US

Bio-templated assembly of inorganic materials is a promising technique for facile bottom-up assembly of complex and unique nanostructures at ambient conditions. Here, viral-templated nanocrystalline gold nanowires were synthesized for use in highly sensitive H2S sensors [...]

A sensing properties study on miniature Au/SnO2 gas sensor for hydrogen sulfide detection

Chang B-W, Ding S-J, Chen R.L.C., Hungkuang University, TW

The purpose of this study was to investigate the sensing properties for self-developed hydrogen sulfide gas sensor. In different temperature treatment and Au nano-particles doping ration, the sensitivity and selectivity of Au/SnO2 gas sensor were [...]

Thin film-resistive gas sensor with SnO2/Au nanocomposite for hydrogen sulfide detection

Chang B-W, Ding S-J, Chen R.L.C., Hungkuang University, TW

A highly sensitive and selective H2S gas sensor has been developed by deposited a SnO2 thin film on an alumina substrate with a spin-coated method. This SnO2 sensing film was be made by a sol-gel [...]
