<p>PCT No. PCT/JP85/00163 Sec. 371 Date Dec. 23, 1985 Sec. 102(e) Date Dec. 23, 1985 PCT Filed Apr. 3, 1985 PCT Pub. No. WO85/04859 PCT Pub. Date Nov. 7, 1985.This invention provides a composition comprising a mixture or a fired product of a material of the general formula Sr(1+x)/2La(1-x)/2Co1-xMexO3- delta (wherein Me: at least one of Fe, Mn, Cr and V; 0</=x</=1; delta : loss of oxygen) and SrMeO3 (wherein Me: at least one of Ti, Zr and and Hf), and a catalyst and a multi-functional sensor using such composition. With this composition it is possible to improve the catalytic performance for cleaning exhaust gas from combusters or internal combustion engines and to improve sensitivity or response characteristics of the sensors for detecting the stoichiometric composition.</p> |
