Abstract

Abstract : Active sites were created on ORR-active titanium oxynitride by low-temperature annealing without changing the nitrogen doping level to determine their origin. Abstract : The oxygen reduction reaction (ORR) active sites on titanium oxynitride (TiO x N y ) have been investigated using catalysts with various nitrogen doping levels, leaving some margins to determine their origin. Herein, low-temperature annealing enhanced the ORR activity of carbon-support-free TiO x N y with a constant nitrogen doping level, indicating that oxygen vacancies produced the sites.
