- Abstract
Tn this study, Tn-doped MoO3 nanobelts were synthesized using a hydrothermal method to investigate the effects of Tn doping concentration on their physical phase, morphology, and room-temperature hydrogen sensing properties. The results revealed that the Tn-doped products were orthorhombic MoOs nanobelts with an average length of approximately 5/im and a diameter of about 200 nm. As the Tn-doping concentration increased from 2 to 6 at %, the room-temperature hyd rogen sensing properties of the nanobelts were gradually enhanced. However, the properties deteriorated when the Tn-doping concentration was further increased to 1 Oat%. The MoO3 nanobelts with a doping concentration of 6at % exhibited the best room-temperature hydrogen sensing performance, with a response of approximately 1.84 to 3000 ppm H2 and a response time of about 42 s. Moreover, the Tn-doped MoO3 nanobelts showed good repeatability to hydrogen and exhibited excellent selectivity and stability.
