The reduction chemistry of the perovskite and perovskite-related compounds, CaRuO3, SrRuO3, BaRuO3, SrIrO3, and BaIrO3, was examined. Samples were reduced at low temperatures (≤ 600°C) by direct reduction with hydrogen gas and by a method that utilized zirconium metal as an oxygen getter. No evidence for oxygen deficient perovskites was observed. In almost all cases, the mixed metal oxide was reduced to form the zero valent platinum group metal and the binary oxide or hydroxide (AO or A(OH)2). One exception was seen in the reduction of SrIrO3 via the getter method where the intermediate Sr4IrO6 was found.
