Abstract Sn-doped indium oxide hollow micron-rods (Sn-In₂O₃ HMs) were prepared by calcination of Sn-doped organic framework compounds (MOFs) which prepared by a simple hydrothermal method. From the results of characterization, the morphology of Sn-In₂O₃ was hollow micron-rod and the specific surface area was large. In addition, Sn element was successfully doped and Sn-In₂O₃ HMs had abundant oxygen vacancy. The investigation on the gas-sensing performance revealed that the Sn-In₂O₃ HMs sensors could detect low concentration of chlorine (Cl₂) and displayed a low detection limit (0.37×10^-9). According to the analysis of gas-sensing mechanism, the excellent Cl₂ sensing properties were ascribed to the hollow structure, large specific surface area and abundant oxygen vacancy. Those mainly derived from the preparation of MOFs template method and the doping of Sn element.

Key words： Sn-doping indium oxide oxygen vacancy chlorine gas sensor
