摘要: Abstract SnO 2 nanomaterials with different morphologies, such as nanofilms, nanorods, and nanowires, were fabricated by sputtering thermal evaporation methods. Their hydrogen sensing properties then investigated. The structural characterizations showed that the in these was tetragonal. surface-to-volume ratio of nanowires increased, leading to an increase effective surface area. Gas sensors based on a reversible response at various concentrations. order nanorods enhanced while peak operating temperature decreased from 250 150 °C, or recovery time became shorter. results indicated sensor effectively increased area demonstrating gas-sensing could be significantly improved changing nanomaterial morphology.
