· K1 Rh1 O3

K1Rh1O3 is an experimental mixed-metal oxide semiconductor compound containing potassium, rhodium, and oxygen in a perovskite-related crystal structure. This material belongs to the family of transition-metal oxides under active research for electrochemical and photocatalytic applications due to rhodium's catalytic properties and the potential for tunable electronic behavior through the potassium dopant. Limited commercial use exists at present; it is primarily of interest to materials researchers exploring novel catalysts, electrode materials, and photocatalytic systems where the combination of earth-scarce rhodium with alkaline-metal doping offers unique electronic and chemical functionality.
