· SrIrO3

Strontium iridate (SrIrO3) is a mixed-metal oxide ceramic compound combining strontium and iridium in a perovskite structure. This material is primarily investigated in research contexts for its electrochemical and catalytic properties, with potential applications in energy conversion and surface catalysis where the combination of transition-metal activity and oxide stability is valuable. Its notable characteristics stem from iridium's high oxidation resistance and catalytic capability, making it of particular interest for oxygen evolution catalysis and fuel cell technologies where alternative to platinum-group catalysts is sought.
