ZnO,SnO and  Zn2SnO4  sensors with Ag2O nanoparticles decorated around, respectively were confirmed to have reduced conductivity due to the catalytic activation of ambient oxygen detection triggered by the ethanol pulses associated with residual Ag2O nanoparticles.This unique reversible catalytic oxidation/redox chemical detection mechanism could bring up new nanoscale chemical sensor design .
