Sb-doped SnO2 nanoribbons (NRs) with a single crystal structure are synthesized via thermal evaporation. H2S gas sensor is developed based on a single Sb-SnO2NR through dual-ion beam sputtering deposition with a mask template. The response of the Sb-SnO2NR sensor has been measured up to 56-100 ppm of H2S at 150 degrees C. More importantly, this sensor shows a response of 10(1.6) toward 100 ppb of H2S at 150 degrees C(25 degrees C), which promotes the detection limit of H2S. The NR-based sensor also exhibits a high sensitivity, good selectivity and long-term stability with a prompt response time, demonstrating good sensing capabilities at room temperature. The mechanism for enhanced sensing performance of Sb-doped SnO2 nanoribbon is discussed. (C) 2015 Elsevier B.V. All rights reserved.
