Abstract
A catalytic structure may be in the form of a ceramic support member having disposed on it a catalytic material which is a fired coating (124a-1, 124a-2) of a catalytic ink. The catalytic ink contains a liquid vehicle, at least one metal resinate compound and fine particles of a refractory metal oxide having dispersed thereon a catalytically effective amount of a catalytic metal component such as platinum or palladium or combinations of two or more catalytic metal components. The resulting catalytic structure may be employed as a catalytic gas sensor (24, 124) and further may include at least one conductor member (130, 132) which provides both temperature sensing of the fired catalytic coating (124a-1, 124a-2) to ascertain the degree of reaction taking place at the surface thereof, and heating of the support member to heat the fired catalytic coating to a temperature high enough to promote the catalytic reaction. The catalytic structure may be prepared by applying to a substrate a coating of a catalytic ink or paste and firing the applied coating.
