METHOD FOR PREPARING PROTON-CONDUCTING PARTICLES CAPABLE OF CATALYZING THE REDUCTION OF OXYGEN OR THE OXIDATION OF HYDROGEN |
摘要 |
A method for preparing particles includes a material capable of catalyzing the reduction of oxygen or the oxidation of hydrogen, the particles being functionalized by polymers including at least one repeating unit bearing at least one proton-conducting group, and the particles being covalently bonded to a carbon material. The method includes the following consecutive steps: a) a step of contacting particles, comprising a material capable of catalyzing the reduction of oxygen or the oxidation of hydrogen, with a compound that is an initiator for ATRP polymerization, the compound comprising at least one group capable of being grafted onto the surface of the particles, whereby particles, onto which a radical of the initiator compound is grafted, are obtained; and b) a step of contacting the particles obtained in a) with at least one monomer having at least one proton-conducting group, whereby the polymerization of the monomer from the above-mentioned radicals occurs. |
