<p> Reactive sputtering, etc., is performed to combine SnO2 and Pt simultaneously by sputtering under predetermined film-forming conditions to form a Pt-doped SnO2 film, and a rutile-structure tin/platinum complex oxide represented by the general formula SnXPt(1-X)O(2-δ) is produced (0.7<X<0.9; 0≤δ<2). The present invention makes it possible to obtain a novel tin/platinum complex oxide having stable catalytic performance due to Pt microparticles (Pt atoms) being densely dispersed in large quantities in SnO(2-δ) so that the Pt oxidation state is fixed. Said oxide can be used in a variety of catalysts, sensor materials, catalytic electrodes, etc.</p> |
