Abstract

A Li–O2 battery with TiN nanoparticles supported on Vulcan XC-72, n-TiN/VC, as the cathode catalyst presented an onset potential for the oxygen evolution reaction (OER) at 2.9 V, contrasting with a mixture of micro-sized TiN and VC (m-TiN/VC), and VC, both at ∼3.1 V. The discharge–recharge voltage gap of n-TiN/VC was estimated to be 1.05 V, which is 390 and 450 mV smaller than that of m-TiN/VC and VC, respectively, at 50 mA gcarbon−1. These indicate that n-TiN/VC can function as both an active ORR catalyst during discharge and an efficient OER catalyst during recharge.
