A new type of multi‐metal oxide gas‐sensing material, CoSnO 3 was synthesized by a simple hydrothermal method, in which CoSn(OH) 6 was used as a precursor, and it was calcined into amorphous CoSnO 3 . The CoSnO 3 nanoparticles were characterized by means of XRD, FE‐SEM, TEM and N 2 adsorption‐desorption analysis. The average size of the CoSnO 3 nanoparticles was of 90 nm. The sensor based on the CoSnO 3 nanoparticles showed good gas‐sensing performances to n‐butanol. The highest response was about 23 to 100 ppm n‐butanol at 200 °C. Moreover, CoSnO 3 nanoparticles exhibits promising candidate material for fast, sensitive and selective detection of n‐butanol.
