Abstract
A method of manufacturing a carbon support with improved porosity and surface hydrophobicity, in which a carbon support with improved porosity and surface hydrophobicity can be manufactured by activating a carbon support by controlling the pressure factor of an activating gas.
Claims18
A method of manufacturing a carbon support, comprising activating a carbon support by reacting the carbon support and an activating gas in a pressure circulation control manner.
A method of manufacturing a carbon support, comprising:
- (i.) subjecting a carbon support to oxidation heat treatment;
- (ii.) activating a pretreated carbon support by reaction with an activating gas;
- and
- (iii.) subjecting an activated carbon support to reduction heat treatment, wherein activating the pretreated carbon support comprises activating the carbon support by reacting the carbon support and the activating gas in a pressure circulation control manner.
