Abstract
In this work, the CoSnO3 nanocubes with p-type semiconductor feature was synthesized via a hydrothermal method. The chemical composition, morphology, and structure of CoSnO3 were characterized by XRD, BET, SEM, TEM and XPS. The CoSnO3 exhibited excellent gas sensing performance to 30 ppm ethanol, including high gas response (22.5), low operating temperature (210 degrees C) and response-recovery time (45 s, 44 s). The prepared CoSnO3 could be used as a promising gas sensing material to detect ethanol.
