Abstract

An aryne-grafted carbon-supported catalyst and a method of preparing the same, and particularly to a carbon-supported catalyst having an organic anchor formed on the surface of a carbon support through aryne cycloaddition in order to improve the durability of a fuel cell catalyst, and a method of preparing the same. It is possible to form a covalent bonding selectively to a carbon support of a fuel cell catalyst in a solution by using 2-(trimethylsilyl)phenyl triflate or the like. In addition, the formed anchor prevents adhesion of metal catalyst particles of a fuel cell, and thus improves the durability of a fuel cell catalyst.
