Mesoporous carbon as support for PtRu catalyst. Electrochemical and fuel cell characterization
With the aim to increase dispersion and minimize the size of metal nanoparticles, a mesoporous carbon was used as catalyst support. Mesoporous carbon with controlled pore size was prepared by carbonization of a resorcinol-formaldehyde polymer. PtRu (1:1 ratio) nanoparticles were deposited onto the c...
