Room temperature sensor based on carbon nanotubes and nanofibres for methane detection

Carbon nanotubes and nanofibres deposited by an electrodeposition technique were utilized to fabricate sensor material for the detection of methane. Carbon nanotubes (CNT) and nanofibres were grown on Si(0 0 1) substrate using acetonitrile (1% v/v) and water as electrolyte at an applied d.c. potenti...

Description
Summary:Carbon nanotubes and nanofibres deposited by an electrodeposition technique were utilized to fabricate sensor material for the detection of methane. Carbon nanotubes (CNT) and nanofibres were grown on Si(0 0 1) substrate using acetonitrile (1% v/v) and water as electrolyte at an applied d.c. potential ∼20 V. Sensing properties were studied with as-deposited CNT films. It was found that the films showed good sensing properties at room temperature.
