EASY CHECKING THE PORE STRUCTURE IN CARBON SUPPRESSED, PGM-BASED CATALYSTS

摘要

A method for forming a carbon supported catalyst includes a step of providing a first carbon supported catalyst having a first carbon supported platinum group metal. Characteristically, the first carbon carrier has a first mean micropore diameter and a first average carbon surface. The first carbon supported catalyst is contacted with an oxygen-containing gas at a temperature of less than about 450 ° C for a predetermined time to form a second carbon supported catalyst wherein the first carbon supported catalyst or the second carbon supported catalyst is acid leached.
