Hydrogen sensing characteristics of thick films of nanoparticles (35 nm diameter) of ZnO, 3% Co doped ZnO, 1% Pt-impregnated ZnO and 1% Pt-impregnated 3% Co–ZnO have been investigated. The last composition exhibits the highest sensitivity for 10–1000 ppm H2, reaching values upto 1700 as well as good response and recovery times at 125 °C or lower. The sensor is not affected significantly upto 50% relative humidity.
