Abstract
A heat treatment method performed to form a particle structure of a carbon-supported metal catalyst includes preparing the carbon-supported metal catalyst by supporting metals on a support including carbon. The heat treatment method also includes applying heat shock to the carbon-supported metal catalyst. The applying heat shock to the carbon-supported metal catalyst includes raising a temperature of the carbon-supported metal catalyst to a first temperature and lowering the temperature of the carbon-supported metal catalyst to a second temperature. A difference between the first temperature and the second temperature is 500° C. to 1,100° C. The applying heat shock to the carbon-supported metal catalyst is repeated at least once. A carbon-supported metal catalyst is prepared by the heat treatment method.
