Hydrogen sulphide gas sensors based on multi walled carbon nanotube

nanosensor based on multi walled carbon nanotube MWCNT for detection of gaseous molecules of hydrogen sulphide in natural gas stream was fabricated . This gas nanosensor was prepared by conventional photolithography and sputtering process for deposition of au as interdigitated electrode IDE on an alumina substrate. MWCNT were dispersed in an organic vehicle , spin coated on substrate and subsequently annealed at 100C to remove the organic vehicle . this study shows that MWCNT can be sensitive to hydrogen sulphide when operate at roon temperature.
