Abstract

Here we demonstrate the preparation and improved hydrogen monitoring properties based on p-NiO/n-SnO₂ heterojunction composite nanofibers via the electrospinning technique and calcination procedure. NiO/SnO₂ heterojuction composite nanofibers were spin-coated on the ceramic tube with a pair of Au electrodes for the detection of hydrogen. Extremely fast response?recovery behavior (∼3s) has been obtained at the operable temperature of 320 °C, based on our gas sensor, with the detection limit of approximate 5 ppm H₂. The role of the addition of NiO into the SnO₂ nanofibers and the sensing mechanism has also been discussed in this work.
