We report for the first time a novel room temperature methane (CH 4 ) sensor fabricated using porous tin oxide (SnO 2 ) nanorods as the sensing material. The porous SnO 2 nanorods were synthesized by using multiwall carbon nanotubes (MWCNTs) as templates. Current versus time curves were obtained demonstrating the room temperature sensing capabilities of the sensor system when exposed to 0.25% CH 4 in air. The sensor also exhibited a wide temperature range for different concentrations of CH 4 (25–500 °C), making it useful in harsh environments as well.
