Abstract
Methods of making an oxygen reduction catalyst are described in which carbon black, one or more metal-containing and/or nitrogen-containing precursor(s) are provided to a reaction zone, and the carbon black is rendered catalytically active. To form this catalytic activity, the carbon black and one or more metal-containing and/or nitrogen-containing precursor(s) are introduced to a reaction zone heated to a temperature of between about 600 and about 1000 degrees Celsius, and maintained together in the reaction zone for a cumulative time between 5 seconds and 240 minutes.
