Abstract

In this paper to determine the formaldehyde used semiconductor sensors based on SnO2, with the
addition of palladium and platinum. Doping SnO2 catalysts can increase the response of the sensor is about 10.
To improve the sensitivity and selectivity, along with stationary temperature were also used transient regimes
