Abstract: Hydrogen sensing characteristics of thick films of nanoparticles (similar to 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 H-2, reaching values upto 1700 as well as good response and recovery times at 125 degrees C or lower. The sensor is not affected significantly upto 50% relative humidity. (c) 2006 Elsevier Ltd. All rights reserved.
