Abstract

TiN was used as an oxygen reduction reaction (ORR) catalyst in a Li-air fuel cell with a non-aqueous/acidic aqueous hybrid electrolyte. The electrochemical properties of the TiN based catalyst and the single cell were extensively investigated. It is suggested that TiN has considerable electrochemical catalytic activity for Li-air fuel cells in a weak acidic solution.
