摘要：

Stable (Pt,Ir) solid solutions, 100 to 200 Å in particle size, were obtained although the corresponding bulk phases are not stable. Ir prevents the sintering of metal particles and alumina reduction to Al during heat treatment in H2. (Pt,Ir) alloys show an increase in hydrogenolysis, compared to Pt, during n-heptane conversion. © 1979 Akadémiai Kiadó.
