Abstract

See full text

Catalysts are provided which can catalyze both the oxygen reduction during the discharge of a secondary air battery and the oxygen production in the recharging of the battery and which are stable at a high potential in the recharging. The invention has been accomplished based on the finding that a catalyst including an oxycarbonitride of a specific transition metal selected from, for example, titanium, zirconium, hafnium, vanadium, niobium and tantalum can catalyze both the oxygen reduction during the discharge of a secondary air battery and the oxygen production in the recharging of the battery and is also stable at a high potential in the recharging.
