Metal Oxide-Based Nanocomposites for Conductometric Gas Sensors

Metal Oxide-Based Nanocomposites for Conductometric Gas Sensors... 

Metal oxide-metal oxide-based nanocomposites, Me 0-Me 0, are also interesting for gas sensor design (Yamazoe et al. 1983 Yamazoe 1991 Ferroni et al. 1999 Yamaura et al. 2000 Comini et al. 2002 Korotcenkov 2007 Gas kov and Rumyantseva 2009). It was established that one of the ways for improving selectivity and stability of metal oxide conductometric gas sensors is the modification of metal oxide, Me O by the introduction of catalytic or structure modifiers, Me 0, in the nanostruc-tured metal oxide matrix and, thereby, the development of nonhomogeneous complex materials, i.e., nanocomposites Me 0-Me 0. It was also expected that other highly sophisticated surface-related properties important for gas sensor applications such as optical, electronic, catalytic, mechanical, and chemical can also be obtained in complex metal oxides and composites.
