Abstract: A method for manufacturing a catalyst support includes: heat-treating a crystalline carbon support in a temperature range from 700° C. to 1100° C. under a vapor atmosphere to increase a specific surface area of the carbon support; and applying a magnetic field to the increased specific surface area of the carbon support to remove an impurity.
