Creation of Oxygen Reduction Reaction Active Sites on Titanium Oxynitride Without Increasing the Nitrogen Doping Level

Abstract

The oxygen reduction reaction (ORR) active sites on titanium oxynitride (TiOxNy) have been investigated using catalysts with various nitrogen doping levels, leaving some margins to determine the origines. Low-temperature annealing enhanced the ORR activity of carbon-support-free TiOxNy with a constant nitrogen doping level, indicating that oxygen vacancy produced the sites.
