Aryne-grafted carbon-supported electrocatalyst and process of preparing the same

A method of preparing an aryne-grafted carbon-supported catalyst, comprising the steps of:

• (A) dispersing a carbon-supported platinum (Pt/C) catalyst to a solution containing a compound represented by the following Chemical Formula 2 dissolved in a solvent to obtain a dispersion:
• (B) introducing at least one reaction catalyst to the dispersion to carry out aryne cycloaddition;
• and
• (C) separating and recovering a compound represented by Chemical Formula 1 modified the carbon-supported platinum (Pt/C) catalyst after the completion of a reaction:
• wherein R1 and R2 are the same or different, and each is independently selected from the group consisting of H, F and C1-C6 alkyl groups;
• —X is selected from —Si(CH3)3 and —F;
• —Y is selected from —O—SO2—CF3 and —H;
• and
• bonding to the carbon support occurs at two sites marked by wavy lines,
• wherein the reaction catalyst is at least one selected from CsF, Mg and KF, and the solvent is at least one selected from CH3CN and THF.
