O2 Na1 Rh1

Sodium rhodium oxide (NaRhO₂) is an oxide semiconductor compound combining alkali metal and transition metal elements, belonging to the family of mixed-metal oxides used in catalysis and electrochemistry research. This material is primarily investigated in academic and industrial research settings for catalytic applications—particularly for oxygen reduction and evolution reactions in electrochemical devices—and represents an emerging class of materials where the sodium component modifies the electronic structure and reactivity of the rhodium oxide lattice. While not yet widely commercialized as a bulk engineering material, compounds in this family are notable for their potential in energy conversion and storage systems where conventional catalysts face cost or performance limitations.
