Title:
METHOD FOR PREPARING PROTON-CONDUCTING PARTICLES CAPABLE OF CATALYZING THE REDUCTION OF OXYGEN OR THE OXIDATION OF HYDROGEN
Document Type and Number:
WIPO Patent Application WO/2013/068318
Kind Code:
A3
Abstract:
The invention relates to a method for preparing particles including a material capable of catalyzing the reduction of oxygen or the oxidation of hydrogen, said particles being functionalized by polymers including at least one repeating unit having at least one proton-conducting group, and said particles being covalently bonded to a carbon material, said method including the following consecutive steps: a) a step of contacting particles, including a material capable of catalyzing the reduction of oxygen or the oxidation of hydrogen, with a compound that is an initiator for ATRP polymerization, said compound including at least one group capable of being grafted onto the surface of said particles, whereby particles, onto which a radical of said initiator compound is grafted, are obtained; and b) a step of contacting said particles obtained in a) with at least one monomer having at least one proton-conducting group, whereby the polymerization of said monomer from the above-mentioned radicals occurs.
